- The present study describes an easy and clean method that makes the pattern of silver colloids by means of microcontact printing. Hydrophilic silver colloids adsorbed on a hydrophobic poly(dimethyl siloxane) (PDMS) stamp are transferred directly to the self-assembled monolayer (SAM) of 4-mercaptopyridine or aminoethanethiol (AET) on an Au-coated silicon substrate. To adsorb silver colloids on the PDMS stamp successfully, adhesion layers such as poly(vinyl pyrrolidone) and stearic acid were pre-treated onto the PDMS stamp. Finally, we obtained a surface-enhanced Raman scattering (SERS) spectrum and image of rhodamine 6G (R6G) on the patterned silver colloids.
