Impacts What was accomplished under these goals?
(1) We have established that a dendrimer-like biopolymer (DLB), namedas "Nano-11", was able to activate dendritic cells and therefore it can be used as an effective vaccine adjuvant. The finding was published in the Journal of Controlled Release (2) We have established a cryo-SEM protocol to image the biofilm formation by pathogenic bacteria including E. coli O157, Listeria monocytogenes, and Salmonella on the surface of cantaloupe rind. We have also found that such a biofilm makes bacteria highly resistant to antimicrobial treatment. (3) We have optimized DLB for the delivery of small molecule drug substances
