(A) UV–vis absorption spectra of colorimetric system for detecting target HIV at various concentrations: 0, 0.01, 0.02, 0.05, 0.1, 0.2, 0.5, 1.0, 5.0, 10, 20, 40, 60, 80, 100 and 120 nM. The inset is the picture of colorimetric system for the detection of target HIV at various concentrations: 0, 0.01, 0.02, 0.05, 0.1, 0.2, 0.5, 1.0, 5.0, 10, 20, 40, 60, 80, 100, 120, 150 and 200 nM. (B) The absorbance increase plotted against target HIV concentration. Inset: calibration cure of absorbance increase at 418 nm vs. logarithm of target HIV concentration.
