Novel nano drug delivery can eliminate tumours

Duke University: Bioengineers have developed a nano-scale delivery vehicle that self assembles with a cancer drug that, in animal models, has eliminated tumors after a single treatment.

Escherichia coli (E. coli) have been genetically engineered to produce a specific artificial polypeptide. When the polypeptide and drug are combined in a container, they spontaneously self-assemble into a water-soluble nanoparticle about 50 nanometers in size, which makes them ideal for cancer therapy.
