NSF clearly states in the topics document that this list should be considered as examples and does NOT represent an exhaustive list of topics and subtopics. The NSF SBIR/STTR program encourages proposals in all areas of science and engineering and rarely rejects proposals for lack of a topical fit with the agency. Therefore, an exact fit into one of these topics or subtopics is not required.
