Microfluidic fabrication of polydiacetylene materials and their applications in colorimetric and fluorometric sensing

초록

Microfluidic platforms have revolutionized both the synthesis and application of polydiacetylene (PDA)-based materials by enabling precise control over their unique colorimetric and fluorescence properties. In the first part of this review, we highlight how microfluidic technologies facilitate the fabrication of PDA materials with improved uniformity, sensitivity, and reproducibility. In the second part, we examine the diverse sensing applications of PDA-integrated microfluidic systems. The intrinsic responsiveness of PDAs to various external stimuli enables their use in chemical, mechanical, temperature, and pH sensing. These integrated systems facilitate dynamic, real-time detection with enhanced analytical precision, reduced reagent consumption, and scalable formats suitable for diagnostics, environmental monitoring, and chemical analysis. Together, these developments highlight the transformative potential of combining PDA materials with microfluidic technologies.
