For cell assays and tissue engineering applications, Nanocrine contact guidance biochips are the only commercially available high-precision etched glass substrates for interrogating the impact of physical topography on cell behavior.

Unlike protein-based patterning or soft materials that degrade, deform, or lack topographical fidelity, our plasma-etched glass offers permanent, micron-scale physical structures with semiconductor-level precision—optically ideal, chemically resilient, easy integration into devices, and reusable across experiments.
