Abstract
|
Princeton University has carried out research to investigate the physics of surface-enhanced Raman scattering (SERS), develop new nanostructure designs to control and increase SERS sensitivity, and to use innovative high- precision large-area nanopatterning technologies to fabricate SERS nanostructures. Particularly, the research has led to (i) a new SERS substrate architecture, disk-coupled dots-on-pillar antenna-array (D2PA), that has a large-area uniform SERS enhancements of several orders of magnitude higher than the highest previously reported, (ii) new nanofabrication technologies for making such SERS substrate over large area with high throughput and low cost; (iii) giant fluorescence enhancement on such substrates, and (iv) applications of such substrates for bio/chemical detections.
