Hello

Both biotechnology as well as biomedical engineering overlap to some extent, but are different .Basically, if a student has interest in medicine, then Biomedical Engineering may be a better choice, whereas if the student is more interested in biology and microbiology, in such a cases biotechnology may be opted.

Biotechnology is the use of living systems and organisms to develop or make useful products, or "any technological application that uses biological systems, living organisms or derivatives thereof, to make or modify products or processes for specific use"

Biomedical engineering is mainly concerned with the facts, theories and models describing biological and clinical phenomena, including other subjects such as physiology, virology, biochemistry, molecular biology and proteomics. It is the most widely applied in development of engineering solutions to both biological and clinical areas.

Hope this helps!
