The NIH Blueprint for Neuroscience Research: Tools and Technologies to Explore Nervous System Biomolecular Condensates (R21 Clinical Trial Not Allowed) funding program supports the development of innovative tools and/or technologies to monitor or manipulate biomolecular condensates (BMCs) in vivo and enable investigators to adopt these tools to answer outstanding questions in basic neuroscience. This research will transform our understanding of the mechanistic role of BMCs in human nervous system health and disease and may serve as the foundation for the development of novel BMC-based therapeutics. Applications are open to researchers in the USA and worldwide. Applicants may apply for up to 275,000 USD for over 2 years . Opportunity ID: RFA-DA-24-039. Letters of intent are due October 14, 2023. Full applications are due November 14, 2023.
