Highly Selective and Sensitive Non-enzymatic Glucose Biosensor Based on Polypyrrole-Borophene Nanocomposite

In this study, a non-enzymatic glucose sensor composed of two-dimensional (2D) borophene-decorated polypyrrole (PPy) nanocomposites (NCs) was developed. The PPy-borophene NCs were prepared using low-cost sonication method. sensing performance the investigated by cyclic voltammetry (CV) technique against various biomolecules such as glucose, maltose, lactose, fructose, and urea. According to electrochemical results, it observed that in concentration range 1.5 24 mM within voltammetric cycle 1 min, PPy-based NCs-based exhibited sensitivities 11.88 μAmM−1 cm−2 213.42 cm−2, respectively. detection limits sensors determined be 0.5 µM 0.04 µM, Furthermore, selectivity measurement results revealed proposed biosensor has remarkably good sensitivity high selectivity, indicating common (glucose, urea) could captured sensor. Consequently, proven potential device for diabetes diagnosis.
