A negative feedback loop based on proton-driven in situ formation of plasmonic molybdenum oxide nanosheets

Abstract

We report a negative feedback loop based on proton-driven in situ formation of plasmonic MoO3-x nanosheets. When the concentration of Cu2+ is below a certain level, the reaction of Cu2+ and glutathione (GSH) produces Cu+ and few protons. However, when the concentration of Cu2+ is above a certain threshold, the reaction of GSH and Cu2+ will generate enough protons to the system which initiates the redox reaction of GSH and MoO3 nanosheets to generate plasmonic MoO3-x nanosheets. This process in turn inhibits the reaction of GSH and Cu2+, which sequesters the excess of Cu2+ from the system. The formation of MoO3-x nanosheets lowers the concentration of the proton in solution and turns off the production of MoO3-x nanosheets. More importantly, the threshold concentration of Cu2+ can be easily regulated by changing the concentration of MoO3 nanosheets.
