Carbon Electrodes for Low Power Heavy Metal Sensing Using MoS_2 Based Resistive Sensors

摘要

This paper describes a facile fabrication technique of Carbon electrodes towards low power Heavy metal sensing. Mos_2, a transition metal di chalcogenide was used as sensing platform. The nature of the Carbon - Mos_2 junction has been investigated. Arsenic solution (Sodium arsenate) solution was taken for heavy metal testing. The sensing capability of the device was measured and validated with the previous reports.
