The purpose of this project was to establish state-of-the art facilities to develop nanoparticle and microparticle encapsulation systems forbioactive components that may improve soldier performance, e.g., nutrient delivery systems or antimicrobial delivery systems. As part of the project we purchased facilitates to fabricate nanoparticles spray drying unit and equipment to characterize the powders produced freeze drying, sputter coating, and scanning electron microscopy. During the course of the project we have developed a wide range of nanoparticle and microparticle delivery systems that can be used to encapsulate, protect, and release bioactive components, including biopolymer complexes, protein nanoparticles,lipid nanoparticles, and microgels. For example, we have encapsulated natural antimicrobials such as essential oils and polylysine,vitamins vitamin A, D, and E, and nutraceuticals curcumin, betacarotene, w-3 fatty acids, polyphenols, and Coenzyme Q10. Vitamins and nutraceuticals may promote soldier performance, whereas antimicrobials may be used to improve the shelf life and safety of rations.
