hi,

since you have future plan to go for research and higher study I would recommend to go for b.sc+ m.sc course in biotechnology. biotechnology is an interdisciplinary stream and past 1 year it has major role in research about vaccines, making drugs , selecting virus and bacteria's. In future the profession would earn a surge of demand in health science related Industry. however b.tech course is more technical oriented and do phd after b.tech you have to do m.tech, which would take 2 years. so it is best to go for bsc + msc course in biotechnology and after that you may apply for ms course in abroad.
