On-demand light-driven release of droplets stabilized via a photoresponsive fluorosurfactant

G. Cheng, Q. Xiao, et al.

This groundbreaking research by Guangyao Cheng, Qinru Xiao, Chit Yau Kuan, and Yi-Ping Ho unveils a rapid method for selectively releasing water-in-oil droplets in microfluidic devices using a photoresponsive fluorosurfactant. With laser-triggered photothermal responses, this innovative approach offers potential for high-throughput screening applications.

Abstract
This paper presents a novel method for the facile and rapid selective release of water-in-oil droplets trapped in microfluidic devices using a photoresponsive fluorosurfactant based on plasmonic nanoparticles. Laser illumination triggers a photothermal response, vaporizing the fluorocarbon oil and creating a bubble that releases the droplet. A fully automated fluorescence-activated droplet release (FADR) platform is developed to demonstrate its potential for high-throughput screening applications.
