A versatile approach for highly sensitive surface-enhanced Raman scattering (SERS) detection of prostate specific antigen (PSA) has been developed based on immune recognition assisted fabrication of gold nanorods (AuNRs) assemblies. Compared with the typical enzyme-linked immunosorbent assay, this SERS immunoassay strategy showed an obviously enhanced sensitivity. The SERS immunoassay for PSA detection has also been successfully applied in diluted human serum samples, showing the promising potential for early diagnosis of diseases in clinical application.
