The gold nanoparticles (Au NPs) localized surface plasmon resonance (LSPR) based detection of prostate-specific antigen (PSA) biomarker was carried out in this work. Au NPs on Si and quartz substrates were synthesized by DC magnetron sputtering method followed by conventional annealing protocol. The functionalization of antibody and PSA with Au NPs was evaluated using a simple drop-cost method. The SPR peak intensity was found to be proportional to the PSA concentration. The redshift in SPR peak position might be owing to the change in refractive index around the Au NPs with the conjugation of antibody and further additional binding of specific PSA at different concentrations.
