NanoBio Corp., of Ann Arbor, Mich., announced a licensing agreement with the University of Michigan that provides NanoBio with rights to an antigen that has been shown to prevent urinary tract infections (UTIs) by eliminating E. coli bacteria in the urinary tract following intranasal vaccination. NanoBio said it plans to pair the UTI antigen with the company's nanoemulsion-based NanoStat adjuvant technology as the intranasal delivery mechanism for the vaccine.
