摘要: Black phosphorus (BP) has a high charge-carrier mobility (similar to 1000 cm(2)V(-1)s(-1)), but the bare BP degrades rapidly in the presence of oxygen and water which limits the application of the BP. In this study, a simple, non-covalent passivation strategy is developed by modifying of the BP with hexamethylendiamine (HA). The functionalized BP exhibits good stability over 4 weeks. The organic phase interdigital electrode which is constructed by stable HA/BP and tyrosinase displays lowest noise signal (0.025 nA) and relatively low detection limit (10 nmol L-1) for bisphenol A. This work provides a new strategy for construction of novel biofuel cell, bioelectronics and biosensors. (C) 2019 Elsevier B.V. All rights reserved.
