Vitreous films of GaGeS composition as a biochip substrate.

Adhesion of protein materials with fluorescent stains to the film of GaGeS composition fabricated by the pulsed laser deposition was investigated. Resistance of the protein markers deposited onto the film to a washing in buffer isotonic solution was established. The obtained results provide the possibility to use these films for the development of protein biochips. [ABSTRACT FROM AUTHOR]
