I'm assuming you're applying to the United States? In that case I would do an internet research to find the top 50 universities in biotechnology/bioengineering. Then do the 2-2-2 method, where you pick your 2 reach schools from the top 10, 2 fit schools from the top 20, 2 safe schools from the top 50. I would also suggest not pursuing a biotechnology degree for your undergraduate degree unless you are 110% sure that's what you want to do. If you pick biology or chemistry, you'll still be able to do research later on but you'll have flexibility if you decide biotechnology isn't for you! Once you are in the college you can find a laboratory that specializes in biotechnology, become an undergraduate research assistant and pursue your graduate degree (which is essential for doing research).
