Hello aspirant

IISER Mohali and IISc Bangalore does not offer btech in nanotechnology, so you cannot apply for the same. Some Colleges which do offer btech in nanotechnology are as follows:-

• SRM institute of science and technology
• School of engineering and technology, jain university
• Amity school of engineering
• Chandigarh university
• NIMS university, Jaipur
• Bharath institute of higher education and research, Chennai
• Bhagwant university

Hope this helps
