title: Patterned porous silicon photonic crystals with modular surface chemistry for spatial control of neural stem cell differentiation.
abstract: We present a strategy to spatially define regions of gold and nanostructured silicon photonics, each with materials-specific surface chemistry, for azide-alkyne cycloaddition of different bioactive peptides. Neural stem cells are spatially directed to undergo neurogenesis and astrogenesis as a function of both surface properties and peptide identity.
