Large scale and well-ordered gold nanoparticle superlattices were fabricated by self-assembly as an active substrate for surface-enhanced Raman scattering (SERS) that can quantitatively detect carbaryl with a detection limit of 1 ppm. These fabricated superlattices with a dimension of several hundred micrometers exhibited high, reproducible SERS activity.
通过自组装制备了大尺寸、有序的金纳米颗粒超晶格,作为用于表面增强拉曼散射 (SERS) 的活性基底,可定量检测克百威,检测限低至 1 ppm。这些具有数百微米尺寸的超晶格表现出高、可重复的 SERS 活性。
