The National Institutes of Health (NIH) is inviting applications for a cooperative agreement aimed at developing in vivo high-resolution imaging technologies for the human inner ear, under the funding opportunity titled "Cooperative Agreement for In Vivo High-Resolution Imaging for Inner Ear Visualization (U01 Clinical Trial Required)." This initiative seeks to support high-risk clinical trials that enhance imaging techniques to visualize inner ear structures with greater detail and accuracy, focusing on improving existing modalities or developing new imaging probes and contrast agents for non-invasive applications. The funding opportunity, which anticipates approximately $2 million to support 2-4 projects annually over five years, is open to a wide range of eligible applicants, including universities, nonprofits, and federal entities. Interested parties should note that applications are due by June 3, 2025, and can find further details at the NIH Grants Information website or by contacting grantsinfo@nih.gov.
