As39S6 films as protein-selective two-dimensional arrays for biochips
Due to the photoresistive properties of films in the As-S system, a two-dimensional array has been formed on a glass substrate using islands of this film. The adhesion of protein materials with fluorescent dyes to the structure obtained was studied. Selective adhesion of protein molecules to islands of a chalcogenide film has been found. The protein markers adsorbed on the film are resistant to prolonged washing in a buffer isotonic solution and water. The results obtained indicate prospects in the study of these films as a material for substrates of protein biochips.
