About this collection

The Institute of Nano Science and Technology (INST) is the first Nano-research institute in India, which was established in 2013 for cutting-edge research in nanoscience and nanotechnology with an interdisciplinary nature in the domains of energy, environment, agriculture, health care, and quantum materials, etc. Scientists at INST with training in physics, chemistry, biology, pharmacy, engineering, and agriculture work together to develop nanotechnology to address scientific issues. In a very short time span, INST has made significant scientific contributions as evidenced from research publications.  In commemoration of the 10th anniversary of the institute, INST has organised an international conference Trends in Emerging Nano Science: Energy, Healthcare & Quantum Materials (TENS-2023) from 5th to 8th November 2023 for the growth of existing collaboration and foster new ones and explore opportunities for students. The collection aims to bring together some of the latest research from members of the INST and speakers at the conference to celebrate the 10th anniversary of the institute and to showcase some of the exciting developments in nanoscience.
