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