Three dimensional multipod superstructures based on Cu(OH)₂ as a highly efficient nanozyme

Abstract

A highly efficient nanozyme system, termed hollow multipod Cu(OH)₂ superstructure (HMPS), has been developed via direct conversion from irregular nanoparticles. The HMPS displayed body size around 150 nm and branch lengths in the range of 150~250 nm. Based on the excellent catalytic property of HMPS, we developed a simple and highly sensitive colorimetric assay to detect urine glucose, and the results are in good agreement with hospital examination reports.
