摘要: Advances in nanophotonics have shown the potential of colloidal metal particles with sharp tips, such as nanostars, to focalize plasmonic electromagnetic fields. We describe this paper performance gold nanostars common surface-enhanced scattering (SES) experiments, including SERS, SERRS, and SEF. The study was carried out for several analytes demonstrated ultradetection nonfunctionalized analytes, by simply depositing on top analyte thin films previously assembled onto a smooth surface.
