A Novel Graphene Oxide-Based Surface Plasmon Resonance Biosensor for Immunoassay



original image

Graphene oxide (GO) is used as a support for binding with proteins. A GO-based wavelength modulation surface plasmon resonance biosensor shows high sensitivity and selectivity for detection of human immunoglobulin G (IgG). When IgG is coupled with gold nanorods (AuNRs), the size increase results in a refractive index change.
