Fluorescent sensors using DNA-functionalized graphene oxide
Liu, Zhenbao; Liu, Biwu; Ding, Jinsong; Liu, Juewen (Springer, 2014-07-02)In the past few years, graphene oxide (GO) has emerged as a unique platform for developing DNA-based biosensors, given the DNA adsorption and fluorescence-quenching properties of GO. Adsorbed DNA probes can be desorbed ... -
Intracellular Detection of ATP Using an Aptamer Beacon Covalently Linked to Graphene Oxide Resisting Nonspecific Probe Displacement
Liu, Zhenbao; Chen, Shanshan; Liu, Biwu; Wu, Jianping; Zhou, Yanbin; He, Lingyun; Ding, Jinsong; Liu, Juewen (American Chemical Society, 2014-12-16)Fluorescent aptamer probes physisorbed on graphene oxide (GO) have recently emerged as a useful sensing platform. A signal is generated by analyte-induced probe desorption. To address nonspecific probe displacement and the ...
