图形化小块纳米金负载PDMS的制备及其作为可重复性SERS基底的潜力
Abstract(#br)A new method for fabricating highly patterned small blocks of nanogold-loaded PDMS, named as PDMS/Au, and their surface-enhanced Raman scattering (SERS) activity are reported. This nanocomposite is based on nanogold impregnated into polydimethylsiloxane (PDMS) elastomer, prepared previously as patterned small blocks using a polypropylene template (PPT), containing 120 small holes. All holes of PPT have the same dimensions 0.5 cm (depth) × 0.6 cm (diameter), allowing to prepare 120 patterned PDMS blocks per batch.
