28.02.2022: Delighted to speak on the National Science Day in the Doordarshan Bangla's live program together with Rajiv Nath from Birla Industrial and Technological Museum, Prof Samit Chakrabarti from Leeds University and Open Academic Research, and Dr Moumita Ghosh from ICeNd, IISc Bangalore and Open Academic Research. It was a lifetime experience to also organise the event with Doordarshan Bangla with so many cooperative hands. Behind the scene, many were involved in organising this program, Dr Varsha Pavithran, Dr Sumantra Pal, Subham Ghosh, Bhaskar Jana, KV Chinmaya, Vinitha Johny, and the complete technical team of Doordarshan. I was overwhelmed to understand how Doordarshan Kolkata Centre despite having minimal technical resources organised this efficiently. One said that to organise the even the Doordarshan Kolkata Centre went through a storm. I am super-happy that this program has influenced Doordarshan to start a weekly program on science communication. Many congratulations to Doordarshan for this.

31.12.2021: We have come up with an exotic flow behaviour at nanometre lenghtscale. We call it a self-drive nanofluidics: https://arxiv.org/abs/2112.15220

13.10.2021: Aren't these signals beautiful? Single molecules are flowing inside a nanofluidic channel. This data certifies that I am a 'molecular plumber'. More than proud sometimes, I feel quite powerful that I can create pipes with cross-sectional diameter as small as our cellular nanopores and able to see light emitting from them one at at time. This means, we are one step closer to 'real' artificial intelligence or synthetic biology.

24.08.2021: Looking forward to meeting the network of the Virtual GAIN21 from 25 Aug to 27 Aug. The annual conference of the German Academic International Network is the largest gathering of German universities, funding agencies and scientists abroad.

24.07.2020: A single-molecule nanofluidic detection method resolving fundamental limit of molecular shot noise with 1D manipulation of sub-3 nm sized single molecule - a potential application for early detection of COVID-19, cancer, and protein misfolding.

Single-molecule confinement with uniform electrodynamic nanofluidicsTo date, we could not engineer Nature's ability to dynamically handle diffusing single molecules in the liquid-phase as it takes place in pore-forming proteins and tunnelling nanotubes. Consistent handling of individual single molecules in a liquid is of paramount importance to fundamental molecular studies
