摘要

Sensors based on mesoporous thin films of phenolic resin and silica, prepared on microinterdigitated electrodes through evaporation-induced self-assembly, exhibit excellent selectivity and reproducibility when sensing aromatic and polar volatile organic compounds, respectively. Moreover, the sensors displayed an ultra-fast response rate for the sensing experiments.
