One of his key inventions is a point-of-care (POC) amperometric device for selective arsenic sensing. This device utilizes electrochemically reduced graphene oxide (ERGO) based reusable flexible electrode strips. The active electrode is prepared through a simple method where a thin film of graphene oxide (GO) is reduced electrochemically at a low DC potential ranging from 0 to −1.5 V. The device is capable of selectively detecting arsenic in field water samples across a wide range of concentrations, with a limit of detection of less than 25 ppb. Notably, the selectivity of the electrode remains independent of the conductivity and total dissolved solids (TDS) levels of the measured water samples collected from various parts of India. The selective detection of arsenic by ERGO is optimized through structural modifications during the electroreduction process.
