Preserved Fulltext
In this study, we present a novel surface-enhanced Raman scattering (SERS) substrate for the efficient capture and characterization of cancer cells using silver nanoparticles-reduced graphene oxide (AgNPs-rGO ...
As a result, MCF7 breast cancer cells are efficiently captured on the AgNPs-rGO substrates, about four times higher than the AgNWs-GO films, and the captured living cells are successfully analyzed by SERS ...
(a) The electric field-assisted pulsed laser reduction for the fabrication of the nano-undulated AgNPs-rGO composite substrate; (b) Capture and surface-enhanced Raman scattering (SERS) analysis of circulating ...
