The result is that any coating, such as an antibacterial layer, would be "self-repairing" after small amounts of damage, as the molecular chains just below the damaged layer re-cover the surface.

This means genes can be re-programmed with small molecules that mimic these environmental factors, what is called molecular medicine.
