Plasmonic coupling interference (PCI) nanoprobes for nucleic acid detection.

Small (Weinheim an der Bergstrasse, Germany) - 4 Nov 2011

Wang Hsin-Neng, Vo-Dinh Tuan

Abstract excerpt

A label-free approach using plasmonic coupling interference (PCI) nanoprobes for nucleic acid detection using surface-enhanced Raman scattering (SERS) is described. To induce a strong plasmonic coupling effect, a nanonetwork of silver nanoparticles with the Raman label located between adjacent nanoparticles is assembled by Raman-labeled DNA-locked nucleic acid (LNA) duplexes. The PCI method then utilizes specific...
