NewsCargo system inhibits E.coli biofilms with a fraction of the antibiotic dose
Scientists have designed a bacteria-targeted cargo system that is capable of inhibiting a quinolone resistant Escherichia coli biofilm using much lower levels of antibiotic. The researchers, from Koç University School of Medicine in collaboration with College of Science, Department of Chemistry, encapsulated the antibiotic ciprofloxacin into superparamagnetic iron oxide nanoparticles ...
