A chemical sensor is a self-contained analytical device that can provide information about the chemical composition of its environment, that is, a liquid or a gas phase. The information is provided in the form of a measurable physical signal that is correlated with the concentration of a certain chemical species (termed as analyte). Two main steps are involved in the functioning of a chemical sensor, namely, recognition and transduction. In the recognition step, analyte molecules interact selectively with receptor molecules or sites included in the structure of the recognition element of the sensor. Consequently, a characteristic physical parameter varies and this variation is reported by means of an integrated transducer that generates the output signal. A chemical sensor based on recognition material of biological nature is a biosensor. The application of chemical sensors has penetrated into the environment, medicine, industry, agriculture, and military. Recent IoT innovation made it possible to connect everyday things to the internet. Chemical sensors play an important role in creating solutions using IoT. In addition, the application of nanomaterials which have high surface to volume ratios and the application of microelectromechanical technology will boost the development of chemical sensors. So, chemical sensors are expected to make great progress in exploring new areas.
In this focused session, we will seek to presentations which reflect the most complete and reliable source of information on recent progress and prospect of high performance chemical sensors using nanostructures of inorganic, organic, and inorganic-organic hybrid materials and low-dimensional materials including quantum dots, 2D materials, nanowires, nanotubes, etc. We also encourage the submission of abstracts related to theoretical calculations and modelling for chemical sensing and the application of chemical sensors in its broadest sense.
Proposed Session Topics:
- Gas sensors and liquid sensors using nanomaterials
- Synthesis of nanostructures for sensitive chemical sensing
- Chemical sensors based on 0D, 1D, and 2D materials
- Surface modification of nanomaterials for selective sensing
- New applications of chemical sensors
- Operando studies on chemical sensing mechanism
- Sensor array, e-nose, and e-tongue
