“…Various non-enzymatic materials, mainly nanomaterials, have been used for glucose sensors, which are known as nanoenzymes. For example, noble metals, 9,10 carbon-based nanomaterials, 11,12 and transition metal nanomaterials (mainly copper, cobalt, nickel, including their metals, 13,14 oxides, 15,16 hydroxides, 17,18 suldes [19][20][21][22][23] ) have been reported as electrode materials for electrochemical glucose sensing.…”
