Nano-sized 'trojan horse' to aid nutrition
August 25, 2008 09:26 AM - Monash University

Researchers from Monash University have designed a nano-sized "trojan horse" particle to ensure healing antioxidants can be better absorbed by the human body. Dr Ken Ng and Dr Ian Larson from the University's Faculty of Pharmacy and Pharmaceutical Sciences have designed a nanoparticle, one thousandth the thickness of a human hair, that protects antioxidants from being destroyed in the gut and ensures a better chance of them being absorbed in the digestive tract.
