I've finally given my college entrance test (The IIT-JEE). And I am expecting a decent rank to join in one of the premier institutes of India. I want to pursue my interests in Nanotechnology, because I think it has a great scope for future research and I want to do the same. But I don't know which branch to take so as to get the knowledge aimed at Nanotech. So I'd like to know via which of the following courses will I be able to learn about Nanotechnology and be more able to pursue further career in it - (these are the probable options for me). Please explain me what I can expect to learn under these branches. 1. Biotechnology - I have a feeling it has something to do with engineering the nanomachines of the nature itself - the cells. 2. Engineering Physics OR (w/ Specialization in Nano Science)* - I am not sure if I can get it with latter, but still, is this the real deal? Also, I'd appreciate if you give me your personal inputs on this, on how to plan my academic future. I'd surely give a good thinking to them.
