  • Supersonic Jet Spectroscopy of Weak H-bonds

    Supersonic Jet Spectroscopy of molecular clusters is being used to investigate weak non-covalent interactions. Such forces play important roles in imparting structures to various biopolymers and also enable them to carry out many functions in living organisms under ordinary conditions that keep the biological systems ticking....

  • Turn-on Sensors for in vivo Imaging

    The quest for unraveling fundamental biological pathways relies heavily upon the ability to precisely visualize strategic molecular players in vivo. Our group works at the interface of synthetic chemistry, molecular biology, and imaging, to develop molecular probes which give a specific ‘ON’ response only in presence of the bio-molecule of interest....

  • Single-Molecule Protein Mechanics

    Single-molecule techniques are novel approaches to understand the structure-stability-function relationship of proteins, especially force spectroscopy methods in studying mechanically relevant proteins. These techniques are also useful to drive chemical reactions and bond-breakage at single-molecule/bond level to understand the reaction mechanism and get the elusive ‘transition state’ properties....

About the Department

Scientists at the DCS explore the link between living systems and the physical laws that govern nature. They study molecules ranging in size as small as water and as large as a virus. The laws that govern interaction in molecules are best studied in well-defined and isolated small molecules. This information becomes applicable to design novel materials with exotic properties, of value to chemical and solar energy industries and to medical applications. To understand working of biological systems, studies are made on structure, dynamics and function of biological molecules. TIFR is a leader in state-of-the-art experimental techniques such as high field NMR, ultrafast lasers and single molecule methodologies.

  • TIFR Annual Chemistry Conference (TACC-2019)

    The Department of Chemical Sciences (DCS) recently hosted the "TIFR-wide Annual Chemistry Conference (TACC 2019)" at TIFR Mumbai during October 16-18, 2019. Please click on the image or link below to download the full program schedule. Photos of the event can be found here.

    The TACC initiative was conceived as an annual TIFR wide activity where faculty colleagues and their students working on chemical problems across TIFR Centers engage in discussions and research presentations. The first edition of the meeting was held last year at the TIFR-Hyderabad campus. TACC-2019 was held in Mumbai at the Colaba campus as a full 3-day event. You can find photos of the event here.

    Faculty members from the department presented snippets of their research in short talks during Oct 16-18. A special talk on P. C. Ray was given by Prof. V. Chandrasekhar on October 17th. 

    Two invited guest speakers, Prof. David Beratan (Duke University, Durham, NC, USA) and  Prof. Steven G. Boxer (Stanford University, Stanford, CA, USA)  presented institute-wide colloquiua on October 16th and 18th respectively. To learn more about the research background of these speakers, click on their names.  

    Students, visiting fellows, and scientific staff presented posters on the 16th and 17th.  You can find the poster booklet containing the poster presentation schedule and graphical abstracts here.  The winners of the best poster awards were: Simli Dey, Ravinder Kumar, and Pallavi Thakur.

    The student organized Chem-Quiz competition returned with a bang on October 17th (Organizers: Shubhangi, Rishi, Pulkit, Rohit, Smitaroopa, Aditya, and Dipin). The Chem-Quiz Winners were Team B (Raghu Ramakrishnan, Kunika Gupta, Mitradip Das, and Saideep). 

    Graduate students (Ayan, Vicky, and Ankur) presented two engaging talks (Music and Chemistry & Chemistry of/for/in space) on October 18th
