Abstract
Recently, MoS2 nanosheets were demonstrated to be able to spontaneously adsorb single-stranded DNA, acting as efficient dye quenchers. We herein report a novel microfluidic biosensor for fluorescent DNA detection based on single-layered MoS2 nanosheets. The proposed platform is simple, rapid and visible with high sensitivity and selectivity.
摘要
最近，二硫化钼纳米片被证明能够自发吸附单链DNA，可作为高效的染料猝灭剂。我们在此报告一种基于单层二硫化钼纳米片的用于荧光DNA检测的新型微流控生物传感器。所提出的平台简单、快速且可视化，具有高灵敏度和选择性。
