The National Institutes of Health (NIH) is offering a funding opportunity titled "Technology Development Research for Establishing Feasibility and Proof of Concept (R21 - Clinical Trial Not Allowed)" aimed at supporting exploratory research for innovative technologies in biomedical research. This initiative encourages high-risk, high-reward projects that focus on developing broad-use technologies, such as laboratory instruments or algorithms, without established feasibility, thereby fostering advancements relevant to the missions of participating NIH Institutes, including the National Institute of General Medical Sciences, the National Institute on Aging, and the National Cancer Institute. Eligible applicants may receive up to $275,000 in direct costs over a two-year period, with applications evaluated based on significance, innovation, approach, and applicant expertise; however, projects that include proof of concept data will be deemed non-responsive. Interested parties should note that the application deadline is May 7, 2025, and can direct inquiries to the NIH OER Webmaster at OERWebmaster03@od.nih.gov for further information.
