2016 journal article

Neurotypic cell attachment and growth on III-nitride lateral polarity structures


author keywords: Gallium nitride; Cell adhesion; Neurons; Semiconductor; Polarity
MeSH headings : Aluminum Compounds / chemistry; Aluminum Compounds / pharmacology; Animals; Cell Adhesion / drug effects; Cell Differentiation / drug effects; Gallium / chemistry; Gallium / pharmacology; Neurons / cytology; Neurons / drug effects; PC12 Cells; Rats; Semiconductors
TL;DR: The designed material configuration is further explored for biochemical sensing, and the lateral polarity scheme may provide a route in assessing the non-specific protein adsorption to this varying nano-topography that drives the subsequent cell response. (via Semantic Scholar)
