Plasmonics-based SERS nanobiosensor for homogeneous nucleic acid detection

A new “turn on” plasmonics-based nanobiosensor for nucleic acid detection has been developed. This nanobiosensor integrating non-enzymatic DNA strand-displacement hybridization for specific target identification with surface-enhanced Raman scattering (SERS) detection is a target label-free and homogeneous nanoparticle-based biosensing system.97
