Phosphorene and other layered pnictogens as a new source of 2D materials for electrochemical sensors

# metadata.dc.description.abstract[].value
Following the great success of graphene as a versatile 2D nanomaterial for the design of electrochemicalsensors, this review focuses on the synthesis, characterization, and electrochemical sensing applicationsof alternative 2D layered structures produced with elements of group VA, also known as'pnictogens.'Among these, phosphorene nanosheets generated from black phosphorous (BP) is by far the mostpopular 2D layered pnictogen; however, bismuthene and antimonene are also gaining interest in thedesign of electrochemical sensors. A perspective is given to the properties of the various layered pnic-togens and factors affecting their stability, which also influence their sensing abilities. Examples usingarsenene are still relatively sparse as this is not an attractive material for biosensing due to its acutetoxicity. Tables with the most meaningful information from the available literature are presented.
