Monodisperse Thermo-responsive Composite Microgels with Core-shell Structure based on Au@Ag Bimetallic Nanorod as Core: Fabrication and Application in SERS Substrate

, , ,
In summary, monodisperse Au@Ag bimetallic nanorod is encapsulated by crosslinked poly(N-isopropylacrylamide) (PNIPAM) to produce thermo-responsive composite microgel with well-defined core-shell structure (Au@AgNR@PNIPAM microgel) by seed-precipitation polymerization method using butenoic acid modified Au@AgNRs as seeds. Their [...]
