Between these two layers is a water-soluble polymer coating less than 10 microns thick.

The drug-coated stents were invented to solve this problem by preventing this re-healing with a drug-and-polymer coating, and they do that very effectively.

Pegasys takes an old hepatitis C drug, interferon, and wraps it in a protective polymer coating of polyethylene glycol (PEG for short) that prevents the interferon from being broken down quickly in the body.

P2i has worked closely with Motorola, who have now implemented the technology in 10 million of their latest phones and the polymer is also coating about 60% of the world's hearing aids.

The outer coating is an acidic polymer that can withstand the harsh stomach environment.

Prof de With and his team found that by attaching these molecules on the end of polymer "stalks" and mixing these throughout the coating, any that are removed by scratches are replaced by a new, self-orientating layer.
