Modification in adsorption properties of graphene during the development of viral biosensors

The well-known effect of the local interaction between graphene and photoresist (LIGF) during creation biosensors is shown to lead non-uniform distribution compressive stresses, which deteriorates adsorption properties graphene, parameter reproducibility, detecting ability influenza B SARS-Cov-2 biosensors. It also that controlling occurrence LIGF areas on a surface by atomic force microscopy or introducing protective layer can minimize non-persistent LIGF. results SARS-CoV-2 imaging in biosensor chips scanning electron microscope are presented. Keywords: biosensors, SARS-CoV-2, virus B.
