"Signal-on" photoelectrochemical biosensor for sensitive detection of human T-Cell lymphotropic virus type II DNA: dual signal amplification strategy integrating enzymatic amplification with terminal deoxynucleotidyl transferase-mediated extension.

本文报道了一种用于灵敏检测人T细胞淋巴病毒II型（HTLV-II）DNA的新型“信号开启”光电化学（PEC）生物传感器。该传感器基于酶促放大与末端脱氧核苷酸转移酶（TdT）介导延伸相结合的双信号放大策略。体系中，GR-CdS:Mn/ZnS纳米复合材料作为光电转换材料，探针DNA（pDNA）作为靶DNA（tDNA）识别单元。TdT介导...
