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...

Quantification of antioxidant capacity in a microemulsion system: synergistic effects of chlorogenic acid with alpha-tocopherol.

Journal of agricultural and food chemistry 2009 Sim WL, Han MY, Huang D

本文报道了一种由12%亚油酸甲酯(或苯乙烯)、29%Tween-20、15%正丁醇和44% 75 mM磷酸盐缓冲液(pH 7.04)组成的水包油微乳液。动态光散射测得亚油酸甲酯油滴粒径19.3 nm、多分散性0.103;苯乙烯体系粒径63 nm、多分散性0.047,并经聚合和扫描电镜证实约70 nm。两种微乳液可稳定两个月。以AAP...
