The National Institutes of Health (NIH) is offering an R21 exploratory/developmental grant aimed at funding innovative research in the development of organ-on-a-chip (OoC) models for dental, oral, and craniofacial (DOC) applications. The primary objective is to validate these microfluidic systems for disease modeling and pre-clinical efficacy studies, promoting a multidisciplinary approach that integrates fields such as bioengineering and computational biology. This initiative is crucial for enhancing drug testing and improving preclinical models, ultimately leading to better clinical trial designs and reducing reliance on animal testing. The total funding available for FY 2025 is $1 million, with individual awards capped at $275,000 over two years. Applications are due by November 19, 2024, and interested parties can reach out to NIH Grants Information at grantsinfo@nih.gov for further inquiries.
