Abstract

Development of a sensor system with high molecular recognition ability was examined for comprehensive detection of numerous volatiles. The built system extracts molecular profiles and classifies odor and VOCs by structurally discernible adsorbents with high selectivity and condensation ability. These adsorbents have multilayer structures where molecular imprinted filter was fabricated on various concentrating materials. Target molecules were selectively absorbed into concentrating layers and other gases were blocked by the nanofiltration. Therefore, the system embedded developed adsorbents enables the detection and discrimination of low-concentrated gases. In addition, nano-filters are optimized and tailored for various applications. These possess not only the flexibility to be easily reconfigured with different properties, but also specific properties to interact with a variety of volatiles. In this study, basic characteristics of molecular filters with reconfigurability was investigated by applying functional materials.
