Researchers at North Carolina State University have determined that the surface texture of gallium nitride (GaN) materials can influence the health of nearby cells. The work is significant because GaN is a material of interest for developing new devices that can control cellular behavior. GaN materials have a unique suite of properties that make them viable candidates for bioelectronic devices: you can tune the charge on the surface of the materials; the materials don’t easily degrade in aqueous environments like the body; and they are nontoxic.
