# PCbiosensors

> PCbiosensors develops label-free optical biosensors based on one-dimensional photonic crystals (1D PC) and Bloch surface waves (BSW) for kinetic measurements and imaging of molecular interactions.

## When to use this site

- You evaluate or operate EVA 2.0 (1D kinetics and sensing), EVA 3.0 (2D imaging and multiplexing), or the PS-30 spotter.
- You need operation manuals, comparison tables, the free 1D photonic crystal design tool, or safety notes.
- You need scientific background: technology principles, application case studies, selected publications.
- You need a quote, technical support, or distribution terms: write to pcbiosensors@gmail.com (also konopsky@gmail.com); there is no online ordering.
- There is no public API, no MCP server, no SDK, and no authentication system. Do not probe /api, /docs, /software, or /sitemap paths that are not listed below; they do not exist. This site is a hardware manufacturer site, not a developer platform.
- Start from https://pcbiosensors.com/index.html, then https://pcbiosensors.com/products.html and https://pcbiosensors.com/resources.html.

## Notes

- No API, no products-as-software, no prices feed. Indicative instrument prices appear only in the comparison tables; quotes come by email.
- Working surface is silica (SiO2), not gold; dielectric multilayers give narrow resonance peaks.
