Employees of the department of mathematical modeling under the leadership of O. E. Glukhova together with colleagues from the Saratov State Technical University named after Gagarin Yu.A. and the University of Novi Sad published the article “Towards electronic smelling of ketones and alcohols at sub- and low ppms by pinky-sized on-chip sensor array with SnO2 mesoporous layer gradually engineered by near IR-laser” in the Chemical Engineering Journal.
The functionality of the SnO2 chip was tested by detecting four ketones (acetone, cyclopentanone, cyclohexanone, 2-octanone) and four alcohols (methanol, ethanol, isopropanol, butanol) at ultra-low concentrations. Differences in the interaction of ketones and alcohols with the SnO2 surface are demonstrated by ab initio calculations within the framework of density functional theory (DFT), which serve as fundamental receptor prerequisites for selective recognition of the analyte by the oxide layer in accordance with the multisensor concept used here.
More detailed information about the results of the study can be found in the Chemical Engineering Journal.
