Dear Student ,

As you have passed your 10th exam, so I would suggest you to focus on your 10+2 board studies as the concepts should be cleared by you at this moment to go into a specific technical topic in depth afterwards .

Well, Nanotechnology is  a popular subject in research areas as well as todays world of innovation .

In the following colleges you may get admission for Nanotechnology for B.Tech after passing 10+2 and JEE exam/equivalent state level exam for some colleges :

• Bharath Institute of Higher Education and Research, Chennai
• SRM University Chennai - SRM Institute of Science and Technology
• Amity School of Engineering, Noida
• University of Technology, Jaipur and others
