Preparation of a Novel Raman Probe and Its Application in the Detection of Circulating Tumor Cells and Exosomes

The Raman probe plays an essential role in sensitive surface-enhanced Raman scattering (SERS) assay. Here, a novel Raman probe was developed by assembling gold nanoparticles in triangular pyramid DNA (TP-Au NPs). Such probe with intense electromagnetic hot spots can provide dramatically enhanced Ram...
