Abstract:
A poly(dimethylsiloxane) (PDMS) stamp was electrolessly plated using a cyanide-free solution. Gold nanoparticles (AuNPs) were transferred from the PDMS stamp to indium tin oxide (ITO), (3-mercaptopropyl) trimethoxysilane modified ITO (MPTMS/ITO), and an ITO substrate electrodeposited with a thin copper film (Cu/ITO). AuNPs formed well-ordered structures which were characterized by field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM), and Raman spectroscopy. Microcontact printing allowed thin AuNPs films to be directly transferred from PDMS to substrate, so is a simple, fast, cheap and environmentally-friendly technique. AuNPs patterned on the ITO substrate exhibited surface-enhanced Raman spectroscopy (SERS) activity which will be investigated in subsequent studies.
