Gold nanoparticle-based signal enhancement of an aptasensor for ractopamine using liquid crystal based optical imaging.

Mikrochimica acta 2019 Wang Y, Wang B, Xiong X, Deng S

本文报道了一种基于液晶(LC)光学成像和金纳米颗粒(AuNPs)信号增强的莱克多巴胺(ractopamine, RAC)适配体传感器。将RAC适配体固定于玻璃片自组装膜上,用于特异性识别RAC;RAC与AuNPs混合后,其羟基可吸附于AuNPs表面形成AuNP-RAC复合物。当该复合物与界面适配体结合时,形成适配体-RAC-AuNP...

Highly sensitive aptasensor based on interferometric reflectance spectroscopy for the determination of amyloid β as an Alzheimer's disease biomarkers using nanoporous anodic alumina.

Biosensors & bioelectronics 2019 Amouzadeh Tabrizi M, Ferré-Borrull J, Marsal LF

阿尔茨海默病是21世纪重大全球健康挑战,亟需可靠生物传感器进行早期诊断。本文首次报道了一种基于干涉反射光谱(IRS)的适配体传感器,用于检测阿尔茨海默病生物标志物淀粉样蛋白β寡聚体(Aβ oligomers)。首先制备纳米孔阳极氧化铝(NAA),随后用3-氨基丙基三甲氧基硅烷(3-APES)修饰孔壁,引入氨基;再以戊二醛(GA)为交...
