M. Tech in Nanotechnology
Tarun Narayan is a Marie curie Early stage researcher at Tyndall National Institute. He completed his 5-year integrated (B. Tech. + M. Tech.) Nanotechnology programme at Amity University, Noida. He worked on the development of surface plasmon resonance-based biosensor for colorectal cancer detection as part of M. Tech. thesis. For the Btech thesis he worked on screen-printed electrode-based immunosensor for Brucella abortus detection. He was working as Junior Research Fellow under DBT-funded project entitled “Nanoenabled biosensor for detection of Neisseria gonorrhoeae” at Department of Biotechnology, Delhi Technological University (DTU), Delhi (Sep, 2017-Aug 2018). During this time, he had synthesized an organic-inorganic nanocomposite (polyaniline-gold) and used it as biosensing substrate for impedimetric detection of N. gonorrhea-specific genes. He has practical skills in fields as varied as design and simulation of sensors, synthesis of organic and inorganic nanomaterials and composites, electrochemical techniques, and fabrication of electrochemical and optical biosensors for varied applications.
RP2: Dissolved ions (Cd2+, Pb2+, Hg+, Cu+, Zn+ ions, etc.) monitoring sensors (ESR2, TYN)
The water quality is influenced by presence of heavy metal ions such as, arsenic, cadmium, lead, zinc, mercury, magnesium etc. Most of these metal ions originate from natural or anthropogenic sources. An excess of these ions level in the surface water causes health risk to human, water-living animals and to the environment. In Europe, the maximum acceptable concentration of these contaminants in water is set by the Water Framework Directing (WFD), and ranges from 80 ng/l for cadmium to 1.2 µg/l for lead. ESR2 will design ion-sensitive multi-sensors on a single substrate and fabricate them using microelectronic processes compatible with mass manufacturing. TYN have full facilities for the fabrication of dissolved ions monitoring sensors and previous experience in fabrication of these type of sensors. The sensing capabilities of the sensors toward the selected heavy metals will be assessed first in laboratory settings and then in a real environment.
