One-step synthesis of non-symmetric CuI nanoplates for a highly sensitive non-enzymatic glucose biosensor†
Abstract
The construction of active nanomaterials on the surface of electrodes is very useful to boost electrochemical properties. Recently, great focus has been given to obtain immensely sensitive and selective glucose biosensors. This study demonstrates the well-controlled synthesis of non-symmetric two dimensional CuI nanoplates via a facile one-pot method in aqueous solution. On one side, the surface of the uniform non-symmetrical CuI nanoplates is covered with teeth-like tips, and on the other side the surface is flat and smooth. The non-symmetrical CuI nanoplate displays very high sensitivity properties in structure-dependent ultra-sensitive non-enzymatic glucose biosensors with a wide linear range, which could be ascribed solely to the non-symmetrical structural morphology. This novel study may perhaps open an innovative way to promote non-enzymatic glucose sensing properties.
