As the official channel partner for the field's most sensitive nanoparticle platforms, Bioparticle brings the instruments and reagents that resolve the size, charge, and surface markers of biological nanoparticles — down to a single molecule, with no calibration curves and no compromises — to your lab. ### Two platforms **Particle Metrix · ZetaView — Next-Generation Particle Characterization Platform.** The ZetaView evaluation platform integrates cutting-edge detection modules for complete biological particle analysis. Designed for reliability, reproducibility, and simplicity, it eliminates manual calibration and provides real-time quantitative data. - Measure size, concentration, zeta potential, and fluorescence simultaneously. - Adaptive sample scanning for unknown particle compositions. - High-sensitivity optics with automated parameter control. - Data you can trust — every scan, every sample. **Pangnostics · Digital Flow Cytometry — Next-Generation Platform.** Pangnostics delivers a breakthrough in particle analysis, bringing single-molecule precision to complex biological systems. By overcoming the detection limits of conventional cytometry, it uncovers hidden subpopulations and generates truly quantitative insights. - Ultra-sensitive detection down to single molecules. - Expose hidden nanoparticle populations beyond traditional limits. - High-dimensional phenotyping with expandable multi-color architecture. - Direct digital counting — no calibration curves, no compromises. ### Inside the instruments — two ways of seeing the nanoscale These platforms read biological particles through complementary physics — tracking how particles move, and characterizing the single molecules on their surface. **Nanoparticle Tracking Analysis (Particle Metrix ZetaView).** Up to four lasers illuminate the particles suspended in the cell, while a camera records the light each one scatters — and the fluorescence from labelled particles — as they move under Brownian motion. The Stokes–Einstein relation converts that motion into a hydrodynamic diameter, and counting the tracked particles in a known volume gives an absolute concentration — particle by particle, no calibration curve required. Tracking → size & concentration; Electrophoresis → zeta potential; F-NTA → fluorescence. **Digital Flow Cytometry (Pangnostics dFC).** Sample flows through a planar microfluidic channel where line-confocal optics and four lasers interrogate a tiny detection volume. Each fluorophore-tagged molecule is counted as it passes — across twelve channels — giving absolute, calibration-free numbers and per-particle phenotypes that bulk methods average away. Count → absolute concentration; Colocalize → multiplex phenotype; Copies/particle → surface density. ### How the methods compare — most of the EV population hides below the floor Therapeutic and biofluid preparations are dominated by 30–70 nm vesicles. Where a method's detection floor sits decides whether you measure the real sample — or a brighter, biased subset of it. | Method | Smallest particle | Label-free size | Per-particle | Absolute count | Copies/particle | |---|---|---|---|---|---| | Western blot / ELISA | bulk (no sizing) | — | ✕ | ✕ | ✕ | | Conventional flow | ~500 nm | ✕ | ✓ | relative | ✕ | | High-sensitivity flow | ~70–80 nm | ✕ | ✓ | bead-calibrated | semi | | Nanoparticle tracking (NTA) | ~10 nm | ✓ | ✓ | ✓ | ✕ | | Single-molecule dFC | ~1 nm | fluorescence | ✓ | ✓ calibration-free | ✓ | ### The measurement evolution — from bulk averages to single molecules 1. **Bulk averaging** — Western blot & ELISA confirm a marker is present, but only as a population average. 2. **Particle tracking** — NTA reads Brownian motion for label-free size, concentration, and zeta, particle by particle. 3. **Single-EV phenotyping** — high-sensitivity flow resolves markers on individual vesicles, but a detection floor still hides the smallest EVs. 4. **Single-molecule digital (now)** — Pangnostics dFC counts individual molecules to ≤35 nm — absolute, calibration-free, with copies-per-particle. ### Applications (nanoparticles in biology) - **Extracellular Vesicles** — size, concentration, and surface markers, with per-EV phenotyping. - **Lipid Nanoparticles** — LNP analysis for drug delivery and mRNA therapeutics. - **Nanobubbles** — size, charge, and stability across diverse media. - **Viruses & VLPs** — characterisation for diagnostics and vaccine development. - **Environmental** — tracking nanoparticles for ecological impact studies. ### Portfolio - Pangnostics dFC — single-molecule digital flow cytometry. - ZetaView Evolution — multiparameter NTA. - Lyophilized Exosomes — reference material for calibration and method development. - F-NTA Antibodies — CD9/CD63/CD81 tetraspanin detection antibodies. - Method Qualification (Services) — scientific, regulatory, and engineering support. --- ## Pangnostics dFC — https://bioparticle.com/pangnostics **Headline:** See the 90% your cytometer is missing. The Pangnostics dFC is an ultra-high-sensitivity single-molecule counter in a familiar flow-cytometry format — counting, sizing, and phenotyping every extracellular vesicle, LNP, viral vector, and antibody that flows through, without a single calibration bead. **Key numbers:** ~100% single-molecule detection efficiency · 4 lasers × 12 detection channels · 1–96 samples per run · 0 standard curves required. ### Why it matters For decades, flow cytometry has driven our understanding of cellular heterogeneity. But when the same instruments are turned on the nanoscale — extracellular vesicles, lipid nanoparticles, viral vectors — a large fraction of every sample stays hidden below the instrument's detection floor. Most EVs are smaller than 70 nm and dimmer than a handful of fluorophores, so they simply aren't counted. Every downstream conclusion inherits that blind spot. Pangnostics dFC closes the gap with a fundamentally different optical design: planar microfluidics and line-confocal detection that count individual fluorophore-tagged molecules directly, with essentially 100% single-molecule detection efficiency. The result is absolute, calibration-free quantitation — and a per-particle view of size, surface markers, and copy number that bulk methods average away. ### How digital flow cytometry works (four steps) 1. **Flow** — A 10 µL sample is drawn into a planar microfluidic chip and flows single-file through a detection channel just a couple of micrometres across, so particles pass the laser one at a time. (Planar microfluidics · ~2 µm detection channel.) 2. **Illuminate** — Four spatially separated lasers (405, 488, 561 and 637 nm) are shaped into a line-confocal light sheet spanning the channel, defining a tiny, evenly-lit detection volume every particle must cross. (4 lasers · line-confocal light-sheet detection.) 3. **Count** — Each fluorophore that crosses the sheet emits a burst of photons recorded by single-photon detectors. Bursts above a noise threshold are counted as individual molecules, with essentially 100% detection efficiency and a very low false-positive rate. (Direct single-molecule counting · ~100% efficiency.) 4. **Phenotype** — Twelve channels read the bursts across up to eighteen dyes at once. Colocalizing signals on the same particle gives a true multi-parameter phenotype — and the copy number of each marker, per vesicle. (12 channels · multiplex colocalization · copies/particle.) ### Key capabilities — six things bulk methods can't do - **Single-molecule sensitivity** — validated detection efficiency near 100% across more than 30 fluorescent dyes. Every photon-emitting molecule is counted — including the dimmest — not estimated from a curve. - **High-plex phenotyping** — four lasers and twelve simultaneous channels resolve surface-marker combinations on individual nanoparticles in a single run; expandable for higher-plex assays. - **Absolute quantitation** — direct digital counting yields true concentrations and biomarker copy numbers — no calibration beads, no reference ladders, no ~20% bead-calibration uncertainty. - **Flexible throughput** — run a single urgent sample or a full 96-well plate on the same platform, with a familiar flow-cytometry workflow and no specialist operator required. - **Reveals heterogeneity** — surfaces the dim, small, and rare subpopulations (well under 1% of total particles) that bulk and commercial high-sensitivity platforms miss by design. - **Reagent authentication built in** — measures the absolute concentration of antibody-dye conjugates that can't be read at 280 nm, plus dye-to-protein ratio, removing lot-to-lot reagent variability as a source of irreproducibility. ### Applications - **Extracellular vesicles & exosomes** — phenotype individual EVs across twelve colors; quantify tetraspanin and engineered-marker copy number and absolute subpopulation concentration for liquid biopsy and EV therapeutics. - **Lipid nanoparticles (LNPs)** — characterize mRNA and gene-therapy LNPs at the single-particle level: payload distribution, surface composition, and encapsulation uniformity. - **AAV & viral vectors** — distinguish full, empty, and partial capsids; measure titer and payload heterogeneity for vector development and release characterization. - **Protein aggregates & complexes** — resolve oligomeric states and RNA-binding protein complexes that bulk methods cannot separate from vesicular populations. - **Analytical & therapeutic antibodies** — authenticate dye-to-protein ratios, quantify aggregation, and verify conjugate concentration. - **Nanoparticle standardization** — reference-grade absolute concentrations make dFC an orthogonal method for cross-laboratory harmonization and reagent QC. ### Rigor & reproducibility Absolute counting removes the calibration drift, curve-fitting, and vendor-dependent reagent variability that compromise quantitative EV flow cytometry. Copy-number and sizing methods have been validated against orthogonal techniques including super-resolution and single-molecule TIRF microscopy, and the platform is designed to support standardized community reporting. Aligned with MISEV2023 reporting and the MIFlowCyt-EV framework; orthogonally validated against super-resolution / TIRF; ~4 orders of magnitude dynamic range. --- ## ZetaView Evolution (Particle Metrix) — https://bioparticle.com/zetaview **Headline:** Watch each particle move, and read its size, charge, and markers. ZetaView Evolution tracks thousands of individual nanoparticles in real time — turning Brownian motion into hydrodynamic size, a whole-cell scan into absolute concentration, an applied field into zeta potential, and fluorescent labels into specificity. One instrument, six measurements, no calibration curves. **Key numbers:** 10–1000 nm particle size range · 6 measurements from one cell · 4 excitation lasers, up to 11 channels · 0 calibration curves. ### The instrument — one bench-top platform, every measurement Up to four excitation lasers, a high-sensitivity CMOS camera, and a quartz-glass measurement cell work together under ZetaSphere® software — so size, concentration, zeta potential, fluorescence, and colocalization all come from the same particles, in a single run. **Inside the platform:** - Up to four excitation lasers — selected from 405 / 488 / 520 / 640 / 660 nm, doubling as scatter and fluorescence sources. - High-sensitivity CMOS camera — records the light each particle scatters, and its fluorescence, particle by particle. - Quartz-glass measurement cell — zeta potential measured directly inside the cell, with no disposables. - ZetaSphere® software — one-click multiparameter acquisition, live statistics, and full sample reporting. - Configurations: Mono (1 laser) · Twin (2) · Quatt (4) · up to 11 fluorescence channels · Made in Germany. ### Six measurements, one sample Nanoparticle tracking analysis follows particles one at a time rather than averaging the whole suspension. That single difference lets ZetaView resolve a polydisperse sample into its true size distribution, count particles in absolute terms, measure their surface charge, and separate a genuine subpopulation from background. - **Particle size distribution** — Brownian motion is faster for small particles and slower for large ones. The Stokes–Einstein relation converts each tracked path into a hydrodynamic diameter, and thousands of particles build a full distribution — not a single average (reports D10 / D50 / D90 and span). - **Concentration Scanning Technology** — ZetaView Evolution sweeps the laser through the entire measurement cell, illuminating each plane in turn and capturing every particle it crosses. Counting the whole volume yields an absolute, calibration-free concentration that stays comparable across sample types and across scatter and fluorescence channels, independent of camera gain or laser intensity. - **Zeta potential** — apply an electric field and charged particles migrate; their velocity reveals the zeta potential, the effective surface charge that governs colloidal stability. Measured in the same cell, on the same particles just sized. Range −500 to +500 mV, pH 1–13. - **Fluorescence detection (F-NTA)** — light scatter sees every particle; add a fluorescent label and ZetaView counts only what carries your marker, separating specific signal from noisy background in the same sample. - **Colocalization analysis (C-NTA)** — two labels, two lasers. ZetaView detects each particle in both fluorescence channels and resolves the population into CD9-positive, CD63-positive, and colocalized double-positive vesicles. C-NTA needs at least two lasers (Twin and Quatt configurations). - **Subpopulation analysis** — resolving a subpopulation by size, zeta potential, and fluorescence together isolates a genuine subset and reports its count, fraction, and characteristic size, separating a true EV subset from background that any single parameter would blur. ### Applications - Extracellular vesicles — size, concentration, and tetraspanin profiling with per-EV fluorescence. - Lipid nanoparticles — size and zeta for LNP stability in mRNA and gene-delivery work. - Viruses & VLPs — titre, integrity, and stability for diagnostics and vaccine development. - Biopharma QC — lot-to-lot consistency and stability studies for GLP/GMP workflows. ### Why ZetaView - **Widely cited platform** — an NTA system established across peer-reviewed EV, virus, and nanomedicine literature. Adopted by research groups and biopharma teams worldwide (users include Medical University of Vienna, Masaryk University, Ludwig Boltzmann Institute for Traumatology, and Steinbeis). - **One cell, one workflow** — size, concentration, zeta, fluorescence, and colocalization on the same particles, no instrument-hopping. - **Data integrity built in** — ZetaSphere® logs database events and predefined settings for reproducible, auditable multiparameter workflows. ### Specifications - **Size range:** 10 – 1000 nm (sample and laser dependent) - **Concentration:** 10⁵ – 10⁹ particles/mL · calibration-free Concentration Scanning Technology - **Zeta potential:** −500 to +500 mV · measured directly in the quartz-glass cell, no disposables · pH 1–13 - **Fluorescence:** up to four lasers (405 / 488 / 520 / 640 / 660 nm) · up to 11 channels · sensitivity < 20 AF488 molecules - **Parameters:** size · concentration · zeta · fluorescence (F-NTA) · colocalization (C-NTA) - **Software:** ZetaSphere® — one-click multiparameter acquisition, live statistics, reporting - **Configurations:** Mono (1 laser) · Twin (2) · Quatt (4) · Made in Germany --- ## Lyophilized Exosomes — https://bioparticle.com/exosomes **Headline:** A known sample, so you can trust the unknown ones. Lyophilized Exosomes are stable, extensively characterized biological particles — positive controls and calibration standards derived from traceable human cell lines. Reconstitute, measure, and benchmark your instrument against a value you can rely on, with no cold chain required. **Key numbers:** source-verified from traceable human cell lines · 4 characterized attributes (size, concentration, markers, morphology) · no cold chain (lyophilized stability) · lot-to-lot batch consistency. ### Why a reference standard NTA gives absolute, calibration-free numbers — but to trust those numbers over time, across operators, and between sites, you need a stable sample of known properties to measure against. A well-characterized EV standard is that anchor: it tells you whether a shift in your data is real biology or instrument drift. Because these exosomes are lyophilized, each vial is shelf-stable and ships without cold-chain logistics — the same lot can benchmark an instrument today and a year from now. Benchmarking in action: run the standard repeatedly and plot each result against its certified value. Points inside the ±2σ band mean the instrument is in control; a systematic shift pushes them past the limits, flagging drift before it reaches your real samples. ### What you get — one standard, four (plus) jobs - **Cross-site validation** — confirm instrument performance across multiple sites and timepoints with a common reference. - **Assay reproducibility** — build reproducibility into EV assays and diagnostic workflows from the start. - **Operator onboarding** — a reliable standard for training lab staff and students on consistent technique. - **QC validation packages** — support QC validation in pre-clinical and commercial pipelines. - **Tested every lot** — each lot tested for size, concentration, protein markers, and morphology. - **Lyophilized format** — long-term stability without cold-chain logistics. ### Used across - Extracellular vesicles — subpopulation tracking using CD9 / CD63 / CD81 markers. - Virology — confirm viral capsid protein presence in particle populations. - Nanomedicine — validate surface modifications of lipid or polymer nanoparticles. - Method validation — anchor instrument qualification and stability studies. ### Reference standard details - **Source:** traceable, ethically sourced human cell lines - **Format:** lyophilized — reconstitutable, shelf-stable, no cold chain - **Characterization:** per-lot testing of size, concentration, protein markers, and morphology - **Markers:** tetraspanin-positive (CD9 / CD63 / CD81) for subpopulation work - **Use:** positive control & calibration standard for NTA and EV assays --- ## F-NTA Antibodies — https://bioparticle.com/fnta-antibodies **Headline:** Turn a particle count into a specific one. Fluorescence-NTA earns its specificity from the label. These antibodies are optimized for the ZetaView® platform — ready-to-use, lyophilized for shelf stability, and targeted to the EV surface markers that tell your vesicles apart from everything else in the sample. **Key numbers:** 3 markers (CD9 · CD63 · CD81) · 1 tetraspanin cocktail kit · 1 IgG isotype control · ready-to-use with minimal prep. ### Why F-NTA reagents — specificity is a reagent decision Light scatter counts every particle in a suspension; fluorescence counts only the ones your antibody binds. The quality of that distinction — the gap between total and specific — depends entirely on the label: its affinity, its fluorophore, and the control you run alongside it. Each antibody here is high-affinity and lyophilized for lot-to-lot consistency, with an IgG isotype control so you can measure and subtract non-specific background instead of guessing at it. ### The reagents (catalog) — five products, one F-NTA workflow - **F-NTA CD9** (detection antibody) — high-affinity CD9 detection antibody for tetraspanin-positive EV subpopulations. CD9 · 488 nm channel. - **F-NTA CD63** (detection antibody) — CD63 detection antibody for resolving the CD63-positive vesicle fraction. CD63 · 561 nm channel. - **F-NTA CD81** (detection antibody) — CD81 detection antibody for the third canonical EV tetraspanin marker. CD81 · 640 nm channel. - **F-NTA EV Tetraspanin Kit** (detection kit) — a ready-to-use cocktail for broad tetraspanin coverage across CD9, CD63, and CD81.
