Research Areas

  • Technologies for Affordable Healthcare
  • Microfluidics and Nanofluidics
  • Fluid Dynamics
Suman Chakraborty has research interests in micro/nano scale fluid dynamics and its applications focused towards sustainable technology goals for promoting good health and well-being of the underserved. The notable discoveries emerging from his fundamental research include: surface roughness-aided slippery flow, massively-amplified ionic-pumping in highly-confined water, sticky-flow of water on nano-engineered hydrophobic interfaces, programmable manoeuvring  of tiny droplets along arbitrary preferential directions, generating controlled microbubbles on portable spinning-disc, reversing thermally-driven spontaneous migration of nano-droplets – defying common scientific intuitions in all cases.  He also introduced niche low-cost bio-inspired fabrication and analytical tools to unveil several hitherto-unresolved mysteries of blood flow in human-body microvasculature, including the collective-dynamics of red blood cells. He innovated a biomimetic tumour-on-a-chip technology for unleashing the mechanisms of cancer progression.
Suman is the inventor of ‘Paper and Pencil Microfluidics’ technology - a new class of electrically-manipulative miniaturized devices that does not require any sophisticated fabrication-facility. This emerged as a backbone of manufacturing niche low-cost medical diagnostic devices, as well as facilitating water desalination and energy-harvesting systems on simple paper-strips. By harnessing such spontaneous ion-water interaction in an interlaced fibrous cellulose network, he further demonstrated electrical power generation using wet textiles, drawing analogies with water-transpiration in living plants.

Suman is a global-pioneer of disruptive diagnostic-technologies for resource-limited settings. His notable device inventions include: portable disc to perform a Complete-Blood-Count test, hand-held blood-perfusion imaging device for early screening of oral cancer, and a new Piecewise Isothermal Nucleic Acid test for infectious disease detection at point-of-care.  He leads a National-level Research and Technology Development Hub on Affordable Healthcare, where his own innovated products are being manufactured by small-scale enterprises. This hub is functional as techno-socio-economic lifeline, empowering rural women with the essential skill-set of delivering primary healthcare-support to the last-mile, and rejuvenating rural livelihood via facilitating sustainable enterprise formation for the unemployed.
