Ultrasensitive self-powered cytosensor
2016
Nano Energy
We developed an ultrasensitive self-powered cytosensor based on biofuel cells (BFC) for the detection of acute leukemia CCRF-CEM cells. The core component of the BFC cytosensor was composed of an aptamer (Sgc8c)-functionalized cathode and a nitrogen-doped graphene/gold nanoparticles/glucose oxidase (NG/AuNPs/GOD) anode, which generated a maximum power output density (P max ) of 115 μW cm À 2 . Once the negatively charged CCRF-CEM cells were captured by the cathode via aptamer recognition, their
