Abstract: 摘要 金和銀奈米粒子皆具有增強拉曼散射的特性。而聚左旋離氨酸是支鏈帶正電,由天然離氨酸聚合而成的水溶性聚肽分子,表面嫁接聚左旋離氨酸其支鏈帶正電的氨基,容易因庫倫靜電力使得帶負電的奈米粒子吸附於聚左旋離氨酸的氨基上,形成一奈米複合薄膜。此薄膜材料可作為表面增強拉曼散射的的基底,我們使用羅單寧6G分子來探討薄膜對於表面增強拉曼散射的影響。
Abstract Both gold and silver nanoparticles have a characteristic of surface-enhanced Raman scattering (SERS). Poly(L-lysine) is a water-soluble polypeptide composed of naturally occurring L-lysine, which contains an amine group on each side chain. The side chain amino group of surface-grafted poly(L-lysine) with positive charge can adsorb nanoparticles to form nanocomposite films. These films can be used as a template for surface-enhanced Raman scattering (SERS). We use Rhodamine 6G to find the effects of film to SERS.
