High-density metallic nanogaps fabricated on solid substrates used for surface enhanced Raman scattering
The Raman signal of adsorbed molecules can be significantly enhanced by utilizing metallic structures with high-density Raman hot spots used as surface enhanced Raman scattering (SERS) substrates. In this work, we develop ...
Real-time DNA detection using Pt nanoparticle-decorated reduced graphene oxide field-effect transistors
A large-area, continuous, few-layer reduced graphene oxide (rGO) thin film has been fabricated on a Si/SiO2 wafer using the Langmuir–Blodgett (LB) method followed by thermal reduction. After photochemical reduction of Pt ...
