The Defense Advanced Research Projects Agency (DARPA) is announcing a forthcoming opportunity related to the Microsystem Induced CAtalysis (MICA) program, aimed at advancing microsystem technologies that integrate molecular catalysts for biological function control. The initiative seeks to explore innovative research areas, focusing on the design, simulation, and fabrication of systems that enhance the dynamic performance of integrated microsystems, particularly through the precise placement of catalytic molecules. This program is crucial for developing advanced capabilities in defense applications, emphasizing the need for collaboration among experts in molecular integration and modeling. Interested parties can reach out to the BAA Coordinator at MICA@darpa.mil for further information, and details regarding the formal Broad Agency Announcement will be available at https://sam.gov.
