The National Institutes of Health (NIH) is the primary agency of the United States government responsible for biomedical and public health research. The NIH conducts its own scientific research through its Intramural Research Program and provides major biomedical research funding to non-NIH research facilities through its Extramural Research Program. Of that, a certain percentage must be granted to small businesses under the SBIR/STTR Program. Main areas of funding include clinical research, genetics, prevention, cancer, and biotechnology.
