Researchers from IIT Bombay have designed a protein-based carrier for delivering drugs into cancer cells.

We have all felt it—the uncomfortable feeling in our nether regions that has us heading to the nearest washroom to empty our bladder. While many of us can hold it until we reach a toilet, those with urinary incontinence, or the inability to prevent the leakage of urine from the bladder, face a severe social and hygiene issue. This condition can be caused by a variety of factors, such as urinary tract infections, kidney stones or neurological disorders.

Silicon-based electronic circuits are continuously getting smaller. The Taiwanese manufacturer
TSMC currently makes chips with the smallest feature of the circuit measuring just 7
nanometers, with millions of such components packed on a single chip. The process of
manufacturing such ultra-dense circuits is complex. Despite world-class control, there are tiny
fluctuations in the nanoscale dimensions. Thus, each transistor is slightly different from another
across chips and even on the same chip. A circuit designer must account for such variations to

The research in our laboratory is focused on designing and developing novel, inexpensive and stable phosphorus based compounds to study their organometallic chemistry and explore their catalytic and medicinal applications. Our group is also focusing on designing multifunctional phosphorus based ligands for making homoleptic soft-soft metal-organic frameworks for catalytic, material and photophysical applications.

Design and development of muti-functional, hierarchically structured, and highly ordered materials is the key to the advancement in the field of materials nanochemistry, and bionanotechnology. These fields are likely to play an important role in driving markets, and economies in the developing countries by fulfilling their high demand towards the improvement in health, and energy sector. Specifically, the formation of biodegradable materials with novel properties, multiple functions, improved efficiency, and higher sensitivity can cater to the demand of health and diagnostics industry.

We have been involved in understanding the mechanism of transport in crowded and active medium. For this, we build statistical mechanical models and solve it either analytically or on a computer, when complicacy of the problem does not allow exact analytical solutions. Availability of single molecule data also makes it possible to compare our results with experiments. A realistic example would be biological cell where presence of cell organelles makes it highly crowded.

Touch screens have become the ubiquitous interface for controlling contemporary electronic devices and incorporated into almost all the new technologies starting from smart phones, computers, flat panel televisions to personal gadgets and household appliances. One of the key components of touch screen is a transparent conducting electrode (TCE) which is optically transparent and electronically conductive. TCEs are also the backbone of optoelectronic devices eg. organic light emitting devices (OLEDs), photovoltaics (PVs), liquid crystal devices (LCDs) electro chromical devices (ECDs) etc.

Our research focuses on chemical reactivity and catalysis. When two molecules react to form product(s), there are different likely pathways that one can think of. Energies of various intermediates and transition states connecting such intermediates involved in the reaction has an enormous effect on the pathway a reaction would proceed through. We employ ab initio and density functional theory computational methods to identify the nature of intermediates and transition states involved in catalytic reactions.

Surface enhanced Raman scattering (SERS) spectroscopy, a powerful contemporary tool for studying low-concentration analytes via surface plasmon induced enhancement of local electric field, is of utility in biochemistry, material science, threat detection, and environmental studies. We have developed a simple, fast, scalable, and relatively low-cost optical method of fabricating and characterising large-area, reusable and broadband SERS substrates with long storage lifetime.

‘High-resolution and non-intrusive’ experimental measurements are indispensible for study of complex fluid flows that are frequently encountered in industrial and environmental situations. In today’s age and technology, it is possible to do so with the help of laser-based optical imaging. Our research focuses on using non-intrusive techniques to study instabilities, mixing, and turbulence in complex flows by capturing a spectrum of length-scales ranging from micrometer to centimeter. This ensures that both large-and small-scale flow features are resolved with considerable accuracy.

Semiconductors and superconductors are generally thought to be two very different types of materials. Indeed superconductors are usually metals, alloys and certain oxides with high electron densities. Semiconductors have much lower electron densities. However there are some semiconductors which become superconducting at low temperatures.
