IIT Kanpur researchers show how lasers can precisely control and steer droplets

Kanpur, May 11 (UNI) Researchers from the Indian Institute of Technology Kanpur, in collaboration with scientists from the Indian Institute of Science Bangalore and the University of Lübeck, Germany, have developed a predictive framework to precisely control the propulsion and breakup of liquid droplets using laser pulses.
The findings, published in the prestigious journal Proceedings of the National Academy of Sciences (PNAS), provide new insights into laser–matter interactions and could advance technologies ranging from targeted drug delivery and inkjet printing to laser-assisted manufacturing and biomedical applications.
The study demonstrates that microscopic liquid droplets can be steered in multiple directions, including forward, backward, or radially outward motion, by carefully tuning the droplet position relative to the laser focus and adjusting the laser pulse energy.
