Ph.D. in Nano Science & Technology


Nanotechnology begins to revolutionize agriculture and allied sectors. Several nano-products have started reaching the farm gate. Many industries have launched nano-product manufacturing units. Thus, there is a need for design and fabrication of nano-enabled agri-inputs (nano-fertilizers, nano-seed invigoration, nano-herbicides, nano-pesticides), biosensors (on-site detection of leaf moisture and nitrogen content, seed sensor, early detection of diseases, on-site residue detection using SERS), food systems (nano-packaging and nano encapsulation of functional foods) besides nano-remediation of pollutants in soil and aquatic systems. The TNAU has developed the regulatory guidelines for the testing, evaluation and use of nano-products in the country. The CANT serves as the torchbearer in India to adopt anf carry forward

Doctoral in Nano Science and Technology course

Doctoral Courses

 After admission, students will undertake courses to understand basics and applications of Nano Science and Technology as per the Choice Based Credit System (CBCS) with a total credit load of 100 credits, of which 75 credits are exclusively earmarked for their Thesis Research.



Doctoral thesis research

After completing the courses in the first year, the students start their thesis research based on the researchable issues identified through the brainstorming session involving external experts. Each student is assigned to an experienced faculty, approved by the Dean of School of Post-Graduate Studies, who would guide the student on his/ her choice of research topic



Research internship

Students are exposed to hands-on-experience with tools and techniques, exchange visits within and outside the country, participation in the international and symposia and conferences besides workshops. Many are encouraged to have internships in other institutes for a couple of months, either in India or abroad.

Student Experiences

It was my big dream to step into TNAU, and I joined here in 2017. The trimester system was new to me, and we can study a lot in a short period of time. The course syllabus was updated, and the faculty members taught us simply and elaborately. The study tours related to research helped as to think outside of the box. The nanotechnology course always holds a special place in our curriculum where there is always plenty of room at the bottom to learn and be interested. This course provides ample opportunities to learn strategies. The presentations and assignments that we do give us more self-confidence and skills when we face fellow researchers. The training and demo sessions on analytical instruments gave us experience in handling and learning. This course will offer a wide area of research and job opportunities in the future.

I am happy to be a part of the TNAU family since my master’s degree and doctoral degree in Nano Science & Technology at TNAU. The courses I learned during my academics helped my carrier. Being an alumnus, I am very thankful for the updated teaching and learning skills. The practical experiences and hands on knowledge increased the interest over my course. The faculty members are friendly and handle us in a peculiar way of teaching, which made us to understand the subject more. The importance of each subject in the course gave us different experiences. The knowledge gained on this course motivated the students to develop new products and provide solutions to the problems in agricultural nanotechnology. The high-end instruments available here imparted knowledge on handling the instruments. This course helped me to understand the concerns and precautions associated with adopting the nanotechnology in agriculture.
