Recently, photothermal therapy (PTT) has attracted tremendous attention because of its high efficacy in tumor ablation and minimal damage to normal tissues. A variety of organic photothermal agents have also emerged in recent years, aiming at replacing their inorganic counterparts, which usually are not biodegradable Among various cyanine derivatives, ICG is one of the most commonly employed medical imaging dyes and approved by US Food and Drug Administration (FDA) for clinical use on patients, which has been widely investigated for photothermal cancer therapy.

Emesis in general is natural defensive mechanism of the body to prevent the absorption of the noxious substances in the Gastro Intestinal tract by forceful expulsion of contents. National Cancer Institute at National Institute of Health explains the phenomenon, ‘Nausea is a subjective phenomenon of an unpleasant, wavelike sensation experienced in the back of the throat and/ or the epigastrium that may culminate in vomiting (emesis). Vomiting is the forceful expulsion of the contents of the stomach, duodenum, or jejunum through the oral cavity.

Periprosthetic infection becomes a dilemma when the signs and symptoms that commonly coincide are absent, or when infection occurs in the immediate post-operative period when the usual biologic markers such as erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are still elevated from the surgical procedure. The use of interleukins has become

Osteoarthritis (OA) is a chronic degenerative disorder of joints, which has multi- factorial etiology. OA is the second most common rheumatological problem and is most frequent joint disease with prevalence of 22-39% in India. Injectable polymeric composite gel are synthesised with tailor-made polymeric nanoparticles to achieve both controlled release and thermo-responsive on application of a heat pad on the desired site. The main objective of the project is to develop an intra- articular drug delivery system for OA using a composite in situ gelling system.

Our research work focuses on indigenous development of low-cost bioresorbable medical bone screw for bone-soft tissue Fixation applications. There is a huge demand for orthopedic devices in India and worldwide. It is estimated that more than 100 million screws are used for bone or soft-tissue fixations per year globally.

To demonstrate proof-of-concept of bioresorbable bone screw prototype composed of novel composite biomaterial with advanced functionality:

The risk of chronic kidney disorder, preeclampsia and other diseases which affect the albumin and creatinine level can be detected at an earlier stage by estimating the albumin and creatinine ratio. According to many reports including WHO 2014, 8-10% of the world population is affected by kidney related diseases. In India, there are more than 10 million cases every year for chronic kidney disease (CKD). Preeclampsia is another life-threatening disorder that occurs during pregnancy (affecting 1 in 20 pregnancies), childbirth and postpartum period.It causes high blood pressure and a

Proteomics is the study of entire protein complement in a cell at a given time. It is a rapidly growing field, and is set to become an integral part of translational research. The implementation of proteomics in clinical research can lead to novel developments in the field of personalised medicine, biomarker discovery. This also provides mechanistic insights about disease occurrence and pathogenesis.

The Biosensors and Bioinstrumentation (BSBI, pronounced busybee) lab works on the development of sensors and instrumentation systems for widescale deployment. The sensors are mostly optical fiber based, although electrochemical sensors also form a part of the lab activities. These sensors and sensing platforms can be adapted to detect a wide variety of chemicals, be they biological or non-biological in origin.

Modern lifestyle is associated with high risk towards several diseases such as obesity, diabetes, cardiovascular heart disease, PCOS and liver / kidney malfunction which are associated with metabolic syndrome arising due to sedentary life style and rich diet. Early diagnosis and lifestyle management is essential in preventing metabolic syndrome in the population.

Disinfection of drinking water, swimming pool water, and water used in washing food processing equipment, surgical instrument, food packaging, etc., is an important step from the health consideration. Variety of disinfectants such as chlorine, sodium hypochlorite and bleaching powder are used for this purpose. These generate free chlorine, which is a very effective biocide even at very low concentrations. However, when concentration of chlorine in water is high, it reacts with humic acids present, producing polychloro-derivatives which are potent carcinogens.

Graphene is a very active adsorbent due its polycyclic aromatic structure and hence can be used for removal of harmful pollutants such as dyes, heavy metals, pesticides and antibiotics from water. It can be most conveniently used in the form of three dimensional graphene (3D graphene). For example, plugs of 3D-graphene (see figure) can be stacked into point-of-use water treatment devices. Key point of the technology is to produce 3D graphene with fully exfoliated single-sheets of graphene. Such a material has both very high surface area and activity.

Subscribing to the view of building ‘molecules with purpose’, we design and develop transition metal complexes for utility as initiators in homogeneous catalysis. We specialise in synthesising well-defined molecular catalysts for academically challenging and industrially relevant transformations through enhanced mechanistic understanding.

In a mammalian system, not all the cells are continuously growing and dividing but many of them remain in a quiescent state even though they reside in a rich growth factor medium. Similarly, in a malignant tumor the population of cell had been found to be extremely heterogeneous. Usually the tumor contains cells ranging from highly proliferative to quiescent category, and thus these cells respond quite differently under chemotherapy treatment. Most often the aggressive cells die, but the quiescent cells somehow survive the chemotherapy.

Cell cycle in eukaryotes is a sequence of molecular events that ultimately leads to precise duplication of cells. Most cells of a multi-cellular eukaryotic organism proliferate only when they sense that they are stimulated by specific growth factors above a certain threshold. In cancerous cells, this growth factor sensing mechanism gets perturbed for more than one reason and the cells start to proliferate even when the appropriate signal is absent.

The study of human cognition includes aspects of thinking, memory, decision-making, learning, problem-solving, as well as other basic and executive functions. Such research can include experiments with the general population, to understand how such cognitive functions operate, as well as with clinical samples, to understand how disruptions in normal cognition can facilitate our understanding of the same.

Children with developmental disabilities including Cerebral Palsy and Autism Spectrum Disorder frequently have speech impairments. Based on the 2011 census, there are around 1.9 million individuals with speech disability in India, of which around 80% completely lack speech or have unintelligible speech. Lack of a functional mode of communication can impede children’s overall social communication, emotional, and cognitive development.
