In vitro assessment of the biocompatibility of chemically modified GaAs surfaces
NanoBiotechnology, 2(1-2), 51–59.
TL;DR:
It is confirmed that the GaAs surface can be made biocompatible for several days based on in vitro tests with HeLa and KB cells and suggested that when the toxicity of theGaAs surface is reduced or eliminated, the cells’viability and spreading depend on the chemical and topographical nature of the surface.
