Quantitative determination of ATP. a PL spectrum of the TC/Apt made of different concentration ratios of TC nanosheets to Apt under the 545-nm excitation. b Corresponding agarose gel electropherogram of TC, Apt, and TC/Apt synthesized with different concentration ratios. c–e Schematic diagram of TC/Apt for biosensing ATP under 545 nm excitation (c). PL spectra of TC/Apt treated with ATP at various concentrations (d), and corresponding scatter diagrams of the relative fluorescence intensity ratio ((F-F0)/F0) versus the ATP concentration (e). f–h Schematic diagram of GO/Apt for the ATP biosensing under the 545 nm excitation (f). PL spectra of GO/Apt treated with ATP at various concentrations (g), and corresponding scatter diagram of relative fluorescence intensity ratio ((F − F0)/F0) versus ATP concentration (h). The insets represent the calibration curve of ((F − F0)/F0) versus ATP concentration. TC/Apt and GO/Apt: 200 μg/mL. ATP: 0.001–10 mM
