A constituent of green tea could help treat cancer by delivering drugs directly to tumours, say scientists.
They used the substance in combination with Herceptin, an anti-cancer drug, in mice and found that it targeted tumours better, was more effective and lasted longer in the blood.
The findings, reported in a paper published the journal Nature Nanotechnology, could help to build better drug-delivery systems.
Joo Eun Chung of Institute of Bioengineering and Nanotechnology, Singapore, and colleagues used the molecule which is found in high abundance in green tea to create a carrier for the anticancer protein Herceptin.
