Fabrication of hydrogels with nanoparticles as surface-enhanced Raman scattered (SERS) substrates and their application in Raman imaging
A polyvinyl alcohol–silver nanoparticle (PVA–Ag NP) hydrogel was fabricated using a simple and facile method; it was used as a substrate for surface-enhanced Raman scattering (SERS). The Ag ^+ ions dispersed uniformly in the PVA network were reduced by NaBH _4 ; this process was termed dipping metho...
