We developed a simple, non-enzymatic approach for the colorimetric detection of glucose based on a gold nanoparticles (Au NPs) assisted silver mirror reaction (AuSMR). The linear range of the concentration of glucose is from 0.04 mM to 1 mM, and the lowest concentration that can be distinguished by the naked eye is 10 nM. This approach has been successfully used for detecting glucose in serum.
