Abstract
- Synthesis optimization of Ag NPs with quaternized chitosan (QCS) was studied.
- The size of Ag NPs was tuned by changing the DS and Mw of QCS.
- QCS/Ag NPs exhibited much better SERS performance than Ag NPs without free QCS.
- QCS/Ag NPs as SERS substrate detected tricyclazole in low concentration of 50Â ppb.
- QCS/Ag NPs as SERS substrate detected Sudan I with the detection limit of 10Â ppm.
