Focused Session 3: Nanostructures and Low-Dimensional Materials for Chemical Sensors
A chemical sensor is a self-contained analytical device that provides information about the chemical composition of a liquid or gas phase. It generates a measurable physical signal related to the concentration of a specific chemical species, known as the analyte. The functioning of a chemical sensor involves two main steps: recognition and transduction. In the recognition step, analyte molecules selectively interact with receptor molecules or sites in the recognition element, causing a physical parameter to change. An integrated transducer reports this variation as an output signal. If a chemical sensor uses biological recognition material, it is called a biosensor. Chemical sensors find applications in medicine, industry, agriculture, the military, and play a crucial role in IoT solutions. Advancements in nanomaterials and microelectromechanical technology contribute to further progress in chemical sensor development. This session aims to provide comprehensive information on recent progress and prospects of high-performance chemical sensors using nanostructures of various materials, including inorganic, organic, and inorganic-organic hybrids, as well as low-dimensional materials like quantum dots, 2D materials, nanowires, and nanotubes. The session also welcomes abstracts related to theoretical calculations and modeling for chemical sensing and the newest applications of chemical sensors.
