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

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 a body size around 150 nm and branch lengths in the range of 150–250 nm. Based on the excellent catalytic properties 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.
