AIE Polymers for Biosensing Applications

Abstract

Polymeric materials featuring aggregation-induced emission (AIE) have been developed as emerging luminescent materials benefiting from the superiorities of facial modification, synergetic effect, smart responsiveness, and outstanding photophysical properties. Incorporating AIE luminogens into polymer fabrication gives the obtained polymeric materials fascinating properties, providing a feasible and effective approach for biosensor construction with fast response, high sensitivity, and excellent stability. In this review, the advancement of AIE polymers for biosensing applications in the recent five years are summarized, and the applications in ion detections of the physiological environment, bio-related molecules detection, bioimaging, and intracellular temperature monitoring will be discussed in detail. Finally, the current challenges and perspectives of these promising materials on future development have been discussed at the end of this review.
