Micro Nano Bio Fluidics Unit

Micro Nano Bio Fluidics Unit

Our group has made exceptional contributions to the Physics of Micro/nanoscale flows, Biofluids, and Soft Matter through original research. We have addressed complex problems at the intersection of Soft Matter and Fluid Physics, developing new insights and technologies. Our studies have elucidated several intriguing advanced physical phenomena through a synergy of experiment, theory, and simulations. The studies have led to significant advancements to existing knowledge in terms of new experimental protocols, unique observations, new theoretical formulation, and critical physical insights hitherto unexplored. Our studies have involved flows inside confined geometries such as microchannels and microcavities, involving particles, drops, and bubbles, with varying viscous and elastic properties, relying on the inherent hydrodynamics or external fields such as ultrasound and magnetic fields. The advancements in physics in several research problems have spurred the development of microfluidics technology for several diagnostics and healthcare applications. In addition, we are also committed to advancing education and training in the field through online courses, workshops, and conferences and by serving on editorial boards and scientific committees.

We are funded by the Institutes of Eminence (IoE) scheme, Govt. of India.
