Recent advances of Au@Ag core–shell SERS-based biosensors
Bimetallic alloy Au–Ag surface-enhanced Raman scattering (SERS) biosensors exhibit ultrahigh SERS sensitivity. Au–Ag SERS-based biosensors have been utilized in biological components detection, including; proteins, antigens antibodies complex, circulating tumor cells, DNA, and RNA (miRNA), etc. Abstract: The methodological advancements in surface-enhanced Raman scattering (SERS) technique with nanoscale materials based on noble metals, Au, Ag, and …
