基于n掺杂ti3c2量子点/氧空位（OVs）纳米复合材料设计了一种高性能自驱动光电化学（PEC）平台，用于灵敏检测林可霉素（Lin）。0D n掺杂Ti3C2QDs与2D BiOBr之间的协同相互作用可以产生迷人的化学/电子耦合界面，从而进一步提高PEC活性，包括有效的电荷转移，扩大光吸收和增加载流子密度。实验结果表明，制备的富含ov的n掺杂Ti3C2QDs/BiOBr van der Waals （vdW）异质结构的PEC响应比缺乏ov的BiOBr强9倍。在此基础上，利用Lin适体开发了一种超灵敏的自驱动PEC适体传感器。该传感器具有较宽的线性响应（1.0 × 10−14mol/L ~ 1.0 × 10−8mol/L）、较低的检出限（3.57 × 10−15mol/L, S/N = 3）、优良的选择性和良好的重现性，为在实际样品中检测Lin提供了一种很有前景的工具。这项工作不仅为各种PEC检测提供了一种通用的方案，而且为开发更高效的PEC生物传感器铺平了道路。
A high-performance self-driven photoelectrochemical (PEC) platform was designed based on 0D N-doped Ti3C2quantum dots/oxygen vacancies (OVs) engineered 2D BiOBr nanosheets (N-doped Ti3C2QDs/BiOBr) nanocomposites for sensitive detection of lincomycin (Lin). The synergistic interplay between 0D N-doped Ti3C2QDs and 2D BiOBr can generate the fascinating interface of chemical/electronic coupling to further boost the PEC activity, including efficient charge transfer, extended the light absorption and increased carrier density. Experimental results demonstrated that the PEC response of the prepared OV-riched N-doped Ti3C2QDs/BiOBr van der Waals (vdW) heterostructures were 9-folds stronger than that of OV-deficient BiOBr. On the basis of the such excellent PEC performance, an ultrasensitive self-driven PEC aptasensor was developed with the assistance of Lin aptamer. The proposed sensor exhibited a wide linear response (1.0 × 10−14mol/L ∼ 1.0 × 10−8mol/L), a low detection limit (3.57 × 10−15mol/L, S/N = 3), excellent selectivity and good reproducibility, which provided a promising tool to detect Lin in real samples. This work not only offered a versatile protocol for a wide variety of PEC detection, but also paved the way for the development of more efficient PEC biosensor.
