Polyelectrolyte mediated nano hybrid particle as a nano-sensor with outstandingly amplified specificity and sensitivity for enzyme free estimation of cholesterol.
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...
