Read all about it : Graphene oxide (GO) sensors can be formed on microporous membranes for the visual detection of peptides, protein, and DNA. Silver nanoparticles (AgNPs) modified with ligands, antibodies, and oligonucleotides adsorb onto the surface of GO nanosheets and quench the fluorescence. Upon addition of analytes, the AgNPs disassociate from the nanosheets, and thus the fluorescence is immediately restored.
