Abstract
ABSTRACT Non-enzymatic glucose sensors have been proposed and widely investigated due to their better stability and higher durability against external environmental conditions compared with enzymatic sensors. In this work, the Cu2O long-range ordered nanoarrays with periodic bamboo-like nanostructure were in situ assembled by 2D electrochemistry method for non-enzymatic glucose detection. Combined with ion sputtering, we developed a portable non-enzymatic glucose sensor based on Cu2O ordered nanoarrays. The sensor exhibits excellent sensitivity and specificity toward glucose and a linear relationship with glucose concentrations ranging from 0.05 to 15 mM. In short, the Cu2O ordered nanoarrays developed with special periodic and long-range order nanostructure are expected to be used for the application of non-enzymatic glucose sensors.
