• DNA microarrays have rapidly evolved to become one of the essential tools to examine expression or mutation of thousands of genes simultaneously. There is a need for alternative patterning methods that must be very simple, reproducible, cost-effective, and eventually transferable to any laboratories for their own problematic situations.

  • Diabetes mellitus is a public health problem affecting millions of people worldwide. Commercially available glucose sensors are enzyme based and has numerous drawbacks including high cost and insufficient long-term stability, both of which originate from the intrinsic nature of the enzymes. This project aims at developing a commercially viable non-enzymatic glucose sensor strip and a glucometer. Electrode surface modified with transition metal and metal oxide nanoparticles have been used for the development of non-enzymatic sensors for the amperometric measurements of glucose.

  • Diabetes is a long term prevailing disease which affects millions of people worldwide. It is a condition where the body fails to utilize the ingested glucose. There has been a dire need for the development of low cost yet effective glucose sensing device. Present day devices are amperometric and works on generated electrochemical signals.

  • The requirement of energy in India has been growing exponentially over the years. Since conventional energy options are futile to tackle this raise, the needs for non-conventional energy sources have become essential. Solar Photovoltaic cell could be one such alternative energy source since solar energy is available abundantly in the world which is renewable, eco friendly and free from pollution.

  • This study proposes the investigation of “Bulk Heterojunction” solar cells consisting of different types of p-type (donor) and n-type (acceptor) network. The various chemicals proposed to be used in this study are metal phthalocyanines, polypyrrole, polythiophene, azo dyes, etc.

  • Quantum dots, also known as nanocrystals, are a special class of materials known as semiconductors, which are crystals composed of periodic groups of II-VI, III-V, or IV-VI materials. Their size ranges from 2-10 nanaometers. At these small sizes materials behave differently, giving quantum dots unprecedented tunability and enabling never before seen applications to science and technology. They have properties that are between those of bulk semiconductors and those of discrete molecules.
