A Catalytic Nanomaterial-Based Optical Chemo-Sensor Array

Abstract

An optical sensor array based on chemiluminescent images from spots of nanomaterials has been employed to recognize odorous samples. The distinctive images obtained from the array permit identification of a wide range of analytes, even homologous compounds.

Assembly of Nanostructures for Taste Sensing

“…These materials are potentially suitable for processing as a chip-mounted sensor array. Na et al found that luminescent efficiencies of the CTL are different for a compound on different nanomaterials [28]. As shown in Fig.…”

Recent Advances in Graphitic Carbon Nitride-Based Chemiluminescence, Cataluminescence and Electrochemiluminescence

“…Zhang and coworkers proposed nanosized TiO 2 as the sensing material to detect ethanol and acetone [82], which was considered as a pioneering work for the combination of nanomaterials and CTL-based chemosensors. Since then, CTL-based chemosensors with the adoption of various nanocatalysts have been intensively researched by many academic groups such as Zhang's [83][84][85][86] [96][97][98][99][100][101] and so on. Due to the high chemical stability, specific structure and composition as well as the catalytic, electronic and optical properties, g-C 3 N 4 can provide greater versatility in carrying out gas adsorption, selective catalytic and sensing processes; therefore, g-C 3 N 4 -based materials may provide new opportunities to develop new CTL-sensing materials.…”
