In this presentation, I will introduce recent progress of non-covalently functionalized single-walled carbon nanotubes (SWCNTs) for applications in chemiresistive sensors. Functional polymers were synthesized by decorating receptor groups, which can have a chemical interaction with target analytes such as ionic species in solution. The chemiresistive sensing layer of SWCNTs was non-covalently functionalized by wrapping with functional polymers. As a result, real-time electrical transduction was achieved upon the injection of chemical analyte with high sensitivity and selectivity. The chemiresistive sensor was integrated with a wireless sensing module for application in real-time wireless detection of analytes. The proposed SWCNT-based sensing platform with functional polymerss can be applied in various fields such as environmental monitoring and healthcare.
