A Thermoresponsive Fluorogenic Conjugated Polymer for a Temperature Sensor in Microfluidic Devices

A new, microfluidic temperature sensor system, based on a thermoresponsive conjugated polymer supramolecule, has been developed. By generating blue-phase polydiacetylene (PDA) sensor droplets using hydrodynamic instability, we were able to monitor the variation of fluorescent intensity of the droplets with respect to the flow temperature.
