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.

Peptides on GaAs Surfaces: Comparison between Features Generated by Microcontact Printing and Dip-Pen Nanolithography
Langmuir, 22(21), 8670–8674.
MeSH headings : Arsenicals / chemistry; Gallium / chemistry; Gene Products, tat / chemistry; Microscopy, Atomic Force; Nanostructures / chemistry; Nanostructures / ultrastructure; Peptide Fragments / chemistry; Spectrum Analysis; Surface Properties
TL;DR:
The detailed surface evaluation showed that the patterns have similar chemical compositions but differ in the bonding among the molecules anchored on the GaAs substrate, which can be utilized in future biorecognition experiments that take advantage of the electronic properties of theGaAs substrate and the tunable behavior of the covalently anchored biomolecules on the surface.
