Nanostructured copper selenide as an ultrasensitive and selective non-enzymatic glucose sensor

CuSe nanostructures exhibit high-efficiency for glucose detection with high sensitivity (19.419 mA mM ⁻¹ cm ⁻² ) and selectivity at low applied potential (0.15 V vs. Ag|AgCl), low detection limit (0.196 μM) and linear detection range (100 nM to 40 μM).
