Ultrasensitive Photoelectrochemical Assay with PTB7-Th/CdTe Quantum Dots Sensitized Structure as Signal Tag and Benzo-4-chlorohexadienone Precipitate as Efficient Quencher.

本文开发了一种超灵敏光电化学（PEC）检测方法，用于监测 microRNA-141（miRNA-141）。该方法以 PTB7-Th/CdTe 量子点（CdTe QDs）敏化结构作为信号标签，以 4-CD（benzo-4-chloro-hexadienone）沉淀作为高效淬灭剂。PTB7-Th 和 CdTe QDs 依次修饰于电极表面...
