Review on nanomaterials-enabled electrochemical sensors for ascorbic acid detection.

This review (with 307 refs.) addresses the recent advances in electrochemical nonenzymatic ascorbic acid (AA) sensors using various nanomaterials as sensing elements. In general, nanomaterials have paved the way for a novel and advanced sensing device due to their unique physical and chemical properties. AA sensors based on noble metals, their nanoparticles, transition metals/metal nanoparticles, alloys/bimetallic nanoparticles, conducting polymers and carbon nanomaterials have been reviewed. Also, there has been a focus on describing the details of many significant articles explaining the design of sensors and utilities of the prepared sensors, so that readers might get the principles behind such devices and relevant detection strategies. Finally, the challenges and prospects for the application of nanomaterials-enabled electrochemical sensors for AA analysis have also been incorporated.
