Any nonprofit organization engaged in biomedical research and institutions or companies organized for profit may apply for almost any kind of grant. Only domestic, non-profit, private or public institutions may apply for NRSA Institutional Research Training Grants. An individual may apply for an NRSA or, in some cases, for a research grant if adequate facilities to perform the research are available. SBIR grants can be awarded only to United States small business concerns (entities that are independently owned and operated for profit, or owned by another small business that itself is independently owned and operated for profit or owned by multiple venture capital operating companies, hedge funds, private equity firms, or any combination of these, and have no more than 500 employees including affiliates). Primary employment (more than one-half time) of the principal investigator must be with the small business at the time of award and during the conduct of the proposed project. In both Phase I and Phase II, the research must be performed in the U.S. or its possessions except under rare and unique circumstances where foreign components are thoroughly justified and necessary to the overall completion of the project. To be eligible for funding, a grant application must be approved for scientific merit and program relevance by a scientific review group and a national advisory council. Normally, SBIR projects are generally performed at least 67% by the applicant small business in Phase I and at least 50% of the Project in Phase II. STTR grants can be awarded only to United States small business concerns (entities that are independently owned and operated for profit and have no more than 500 employees) that formally collaborate with a university or other non-profit research institution in cooperative research and development. The principal investigator of an STTR award may be employed with either the small business concern or collaborating non-profit research institution as long as s/he has a formal appointment with or commitment to the applicant small business concern and is willing to devote at least 10% effort (1.2 calendar months) to the project. At least 40% of the project is to be performed by the small business concern and at least 30% by the non-profit research institution. In both Phase I and Phase II, the research must be performed in the U.S. and its possessions except under rare and unique circumstances where foreign components are thoroughly justified and necessary to the overall completion of the project.

Intended beneficiaries: Nonprofit Organization, For-Profit Organization and Unrestricted by Individual Type.
