Islamic Azad University’s scientists have developed a nanosensor that is based on carbon nanotubes (CNTs). The nanosensor, with the help of nanocomputational methods, can be operated at ambient thermal conditions.
According to Leila Mahdavian, Assistant Professor of Islamic Azad University at Doroud branch, almost all metallic sensing devices are capable of working at thermal conditions greater than 250°C, and creating a CNT-based sensor is possible to make it function even at ambient thermal conditions.
Mahdavian further commented that such sensors developed from single-walled CNT exhibit rapid reactions and intense sensitivities at room temperature and thus can be used for identifying materials at both high and low concentrations rates.
Leila Mahdavian employed Monte Carlo and Langevin techniques to develop the nanosensor and attained positive results by identifying and sensing environmental contaminants and alcohols. The nanosensors can be utilized for identifying corrosion in metal parts that result in pipeline leakages and other major damages.
