本文作为概念验证,证明姜黄素与壳寡糖乳酸盐(COL)可在二氧化硅纳米颗粒表面自组装形成纳米杂化颗粒(NHPs)。NHPs粒径25–35 nm,以SiO2纳米颗粒为核,外层为姜黄素-COL,厚4–8 nm。与游离姜黄素相比,NHPs荧光强度被猝灭且发射峰红移约50 nm,归因于内滤效应和/或同一颗粒表面姜黄素分子间的同种荧光共振能量转...

Amplification of resonance Rayleigh scattering of gold nanoparticles by tweaking into nanowires: Bio-sensing of α-tocopherol by enhanced resonance Rayleigh scattering of curcumin capped gold nanowires through non-covalent interaction.

本文报道了一种基于共振瑞利散射(RRS)的光学生物传感器,用于检测α-生育酚(α-tocopherol, α-TOH)。作者通过绿色合成法,在姜黄素和十六烷基三甲基溴化铵(CTAB)存在下,以温度调控将金离子还原为金纳米线(Au NWs)。在45 °C下可得到直径约20–25 nm、长度大于1 µm的细长Au NWs,其RRS信号比...
