Innovation alert: self-healing paint

Scientists in the US have developed a car paint film that's capable of self-healing when scratched, MSNBC reports.

The University of Southern Mississippi has developed a paint coating that contains a form of polyurethane that when damaged and then exposed to sunlight stretches itself across scratches.

While testing is still underway on the coating, a number of applications are being suggested for easily scratched devices including electronics, phones and MP3 players.

Made from a derivative of the chemical compound chitin (a naturally occurring form of glucose), the new coating also boasts impressive environmental credentials.
