These last ten years, smaller, less expensive, and higher performance sensors are required for gas sensing applications. To date no true detection principle has been recognized as the best candidate for such application. Microsytems or Micro/Nano ElectroMechanical Systems (M/NEMS) used as gravimetric detectors are among the probable candidates. The technology can indeed be manufactured en masse and can provide multi-gas analysing platform. In this paper, we present a comprehensive overview of micro / nano sensors based on the gravimetric effect to detect an absorbed gas on top of their surfaces. The paper provides a comparison between different electromechanical devices (Bulk...

A gold (Au) electrode was modified with (3-mercaptopropyl) trimethoxysilane (MPS) by self assembly method and Palladium (Pd) was electrochemically in-situ incorporated on it towards achieve the electrocatalytic reduction of chemical warfare agent sulphur Mustard (SM) at room temperature. Scanning electron microscopy (SEM) and Energy dispersive X-ray analysis (EDX) revealed the presence of Pd in the self assembled layer of MPS. The present modification indicated one electron involvement in the electrocatalytic reduction of SM in addition to it is an irreversible adsorption controlled process. A linear response in the reduction current for SM was obtained in the range between 0.638×10−4M and...

In this paper, bisphenol A (BPA) was successfully deposited on an indium-tin oxide (ITO) electrode by the method of multiple sweep voltammetry. The BPA deposition was found to be affected by the upper potential limit of the multiple sweep voltammetry, the voltammetric sweep number, pH value and BPA concentration. The resulting BPA deposit showed excellent redox activity in an appropriate potential range between −0.2V and 0.4V as well as high ionic-electronic conductivity, revealed by ex-situ voltammetry and scanning electrochemical microscopy. On the basis of redox reactions of the BPA deposit on the ITO electrode, an electrochemical sensor for monitoring the...
