Fabrication of paper-based SERS substrate using a simple vacuum filtration system for pesticides detection

Abstract

Herein, we describe a simple and cost-effective fabrication of paper-based SERS substrate by coating poly(diallyldimethylammonium chloride) (PDADMAC) and gold nanostar (AuNS) on the filter paper using a vacuum filtration system....
