Fig. 7From: A Graphene Oxide-Based Fluorescent Aptasensor for the Turn-on Detection of CCRF-CEMSpecificity of the fluorescent aptasensor for CEM. The fluorescence intensity rate (F/F0) of GO-apt fluorescent aptasensor in the presence of CEM cells, Ramos cells, H22 cells, and 293T cells, respectively (1 × 106), where F0 and F are the fluorescence intensity without and with detection cells at 518 nm. Excitation 490 nmBack to article page
