 Organic field-effect transistors (OFETs) are electronic devices in which t
 he drain current is controlled by an applied gate voltage. When coupled wi
 th appropriate recognition materials\, OFETs can serve as sensitive platfo
 rms for chemical sensing. Herein\, we employed an extended-gate configurat
 ion as a chemical sensor design for analyte detection in aqueous media. Am
 ong recognition materials\, biological materials such as enzymes and antib
 odies have been widely employed because of their high specificity for thei
 r analytes based on the lock-and-key recognition principle. However\, the 
 range of detectable analytes is limited by the availability of suitable bi
 ological recognition elements. Therefore\, synthetic receptors based on mo
 lecular recognition chemistry offer a promising approach to designing reco
 gnition sites. In this study\, molecularly imprinted polymers (MIPs) were 
 applied as recognition materials for selective detection. MIPs provide rec
 ognition sites complementary to analytes through polymerization in the pre
 sence of template molecules followed by template removal. Quantum chemical
  calculations can guide their design by evaluating interactions between th
 e template and monomers. These recognition sites contribute to selective d
 etection even in the presence of interferents. In contrast\, cross-reactiv
 e responses of supramolecular receptors can be combined with pattern recog
 nition methods to discriminate multiple analytes. Furthermore\, the integr
 ation of microfluidics with the extended-gate-type OFET facilitates real-t
 ime monitoring.&amp\;#13\; This presentation will highlight advances in OF
 ET-based chemical sensing through the integration of organic electronics\,
  molecular recognition chemistry\, and microfluidics.
