Siddesh Umapathi, Harish Singh, Jahangir Masud, Manashi Nath
Abstract
CuSe nanostructures exhibit high-efficiency for glucose detection with high sensitivity (19.419 mA mM<sup>−1</sup> cm<sup>−2</sup>) and selectivity at low applied potential (0.15 V <italic>vs.</italic> Ag|AgCl), low detection limit (0.196 μM) and linear detection range (100 nM to 40 μM).
