5277 372 Cu2(OH)3NO3 detect biothiols in human blood serum On the basis of the oxidase-like catalytic of Cu2(OH)3NO3 nanosheets, a simple, quick, sensitive, and selective colorimetric assay was developed to determine biothiols. More interestingly, this technique was successfully applied to detect biothiols in human blood serum, suggesting it has a hopeful prospect for diagnostic in the relevant application.
