Abstract
A donor capable of controlled release of nitric monoxide and a prosthetic implant whose surface is coated with this donor are disclosed. The donor comprises a main chain of an organic polymer and a side chain that is covalently linked to the main chain and has a diazeniumdiolate functional group. The donor for controlled release of nitric monoxide exists in a fluid state such as liquid at room temperature and undergoes a sol-to-gel phase transition at a physiological pH as the temperature increases above the critical temperature. The critical temperature of the phase transition is in the range of 25 to 35° C., and the gel is a hydrogel without chemical cross-links.
