Applied Physics Particle Portfolio
Functionalized Assay & Diagnostic Particles
Choose functionalized particles around conjugation chemistry, surface group, core material, size, concentration and assay workflow.
Material → Measurement Objective
Choose particle material from the method—not from the product name
| Material / family | Start here when the requirement is… | Quote variables |
|---|---|---|
| PSL / polystyrene latex | Monodisperse particle-size references, particle-counter/optical calibration, aerosol work, or deposited wafer references. | Instrument/application, nominal size(s), form/concentration, quantity, certificate/traceability. |
| Silica / SiO₂ | Silica reference behavior, contamination-wafer work, optical/material research, or functionalized silica formulations. | Size, surface treatment/functionalization, powder vs suspension, solvent/concentration, quantity. |
| Borosilicate / glass | Powder/particle-size measurement and methods where glass material properties and available size ranges are appropriate. | Method/instrument, nominal size/range, quantity, sample preparation and documentation. |
| Fluorescent / dyed polymer | Imaging, tracking, optical method development, method visibility or research requiring a colored/fluorescent signal. | Size, color/excitation-emission, surface chemistry, dry/suspension form, concentration/quantity. |
| Functionalized / assay particles | Conjugation, binding, lateral-flow, diagnostic or assay-development workflows. | Core material, size, functional group/coating, concentration, conjugation target and assay conditions. |
| Magnetic / metallic nanoparticles | Research workflows where magnetic response, plasmonic/optical properties or specialized surface chemistry are part of the method. | Composition, size, morphology, coating/functionalization, concentration and application. |
Make the particle inquiry quote-ready
- Instrument, method or end application
- Particle material / composition
- Nominal size or multi-size set
- Dry powder, suspension, concentration or deposited format
- Surface chemistry / fluorescence / coating when relevant
- Package size / quantity and needed date
- Certificate, traceability or other documentation requirement
Do not let the catalog make the engineering decision
Applied Physics has overlapping particle families and many individual size SKUs. The correct quote should be driven by the customer's method and required reference properties—not by whichever product title happens to rank first.
For an accurate quote: use the product quote control so the selected product, variation and quantity remain attached to your request.
