Drug-resistant Bacteria – Designing Nanoparticles For High Antibiotic Doses

Featured Article Academic Journal Main Category: MRSA / Drug Resistance Also Included In: Biology / Biochemistry Article Date: 06 May 2012 – 12:00 PDT email to a friend printer friendly opinions Current Article Ratings: The scientists have been working towards this goal by developing a nanoparticle that invades the immune system, targeting the infection sites, and subsequently release a focused antibiotic attack. According to leading author, Aleks Radovic-Moreno, who is an MIT graduate student, this strategy would lower the side effects of some antibiotics and protect the beneficial bacteria that commonly live in the human body. The new nanoparticles were created from a polymer capped with polyethylene glycol (PEG), which is commonly used for drug delivery due to its nontoxic properties and because it can help to transport nanoparticles through the bloodstream without being detected by the immune system.
