Research Topic:
MRI (T1- Weighted) Activated Theranostic

The advances in genomics, proteomics, and bioinformatics have directed the development of a new type of healthcare system to reduce drug abuse, safety, and precise treatment. In search of an innovative product for health care, the term, “theranostic” gained interest in clinical science.  It is an appealing formulation in a combination of diagnosis and therapy to improve the biodistribution and systematic administration of therapeutic in the target place. Importantly, it could be provided clear-cut solution for long-time pending diseases, namely, genetic diseases and oncogenic diseases. The present needs motivate the organic, inorganic chemists, physicians, biotechnologist, nanotechnologist, and pharmacologist work together to develop “theranostic” as future of personalized healthcare. In this context, by judicious selection of suitable chemical architectures that can interact with overexpressed endogenous reductase enzymes in hypoxic tumors and consequently disintegrate the nanodevices for the release of the chemotherapeutic. The sequential ‘turn-on’ visual and T1- MR modalities of the nano-delivery system will provide information on the real-time drug release and its activation. At the same time, at variable magnetic field hyperthermia will show synergism with chemotherapy. Finally, by providing real-time feedback on the efficacy of targeted therapeutic interventions by multi-modal readouts such as optical and MR (T1/T2) signals, the theranostic nanomedicines can be used to facilitate (pre-) clinical analysis, and approach toward personalized medicine.

Fluorescent Probes

Understanding the chemical transformation at the molecular level in the cellular milieus is challenging.  It motivates the chemist to search for new ways to learn the biological system. Thus bio-inspired emerging strategy for fluorescent-based bio-imaging is to sort and identify the species of interest within this complex microenvironment by exploiting differences in molecular reactivity. Currently, we are interested to develop fluorescent probes to detect pH of cell organelles, cell senescence, Alzheimer’s disease, information on cell cycle, etc.
