Here we described a novel approach of CdTe quantum dots fluorescence probes to improve the detection of proton flux through F1F0-ATP by ATP synthesis. It was found that both the CdTe quantum dots (535nm, 585nm) was attached on chromatophores, respectively, was not only dependent on each of them, but also the micro environment interfering was a little (about 5-6%) , if in the presence of 100 time gradient. So that，CdTe quantum dots used as the smart pH probes monitoring proton flux driven by ATP synthesis for detection various virus simultaneously. Furthermore, a model of steady Double Diffused Layer of CdTe quantum dots on surface of chromatophores was proposed. If would be so, it would be extended to optical coder detection of various viruses in late.
