The Department of Health and Human Services, specifically the National Institutes of Health, is seeking proposals for the Miniaturization and Automation of Tissue Chip Systems (MATChS) through a Small Business Technology Transfer (STTR) program. The goal of this funding opportunity is to support the development of bench top, portable, automated, self-contained systems that maintain 3D tissue constructs and provide biologically relevant outputs of tissue health and function. The technology should be able to automate tissue preculture and loading, system operation, perfusion systems, and cell culture conditions. It should also include in-line sensors for monitoring and sensing, as well as software for instrument control and data processing. The system should be cost-effective, mass producible, and robust. The performance of the system should be characterized and validated, and the applicant should propose quantitative metrics for evaluating progress. The long-term goal is to achieve technological advances that enable the routine use of tissue chips in safety and efficacy assessment of therapeutics. The funding opportunity is open for Phase I, Phase II, and Fast-Track grant applications, with a project duration of up to 2 years. The application due dates are February 22, 2024, February 24, 2025, and February 23, 2026. More information can be found on the grants.gov website.
