A Schematic diagram of the CEAS highly sensitive fluorescence detection system. B Feasibility validation of the CEAS highly sensitive fluorescence detection system. C Incubation time optimization of the CEAS highly sensitive fluorescence detection system. D Fluorescent signal responding to 1 fM, 10 fM, 100 fM, 1 pM, 10 pM, 100 pM, 1 nM and 10 nM of HPV16. E Linear correlation between the colorimetric intensity and the logarithm of target concentrations ranging from 100 to 107 fM. F Specificity validation of the CEAS highly sensitive fluorescence detection system. G Stability validation of the CEAS highly sensitive fluorescence detection system. Error bars represent standard deviations of three independent experiments. *P < 0.05, N no statistical difference
