Described herein are nitric oxide releasing materials, methods of making nitric oxide releasing materials, and devices including nitric oxide releasing materials. The nitric oxide releasing material includes a polymer matrix having a plurality of polysiloxanes and nitric oxide-donating crosslinking moieties that covalently crosslink the polysiloxanes. Blood clotting or adhesion of a bio-material to a surface, as well as biofilm formation can be prevented using the methods and materials described.

Provided according to some embodiments of the invention are methods of forming co-condensed silica particles. In some embodiments, the methods include reacting a thiol-containing silane and a backbone alkoxysilane in a reaction solution that comprises water to form thiol-functionalized co-condensed silica particles, wherein the thiol-functionalized co-condensed silica particles include a polysiloxane matrix and at least some of thiol groups are present within the polysiloxane matrix; and reacting the thiol-functionalized co-condensed silica particles with a nitrosating agent to provide the S-nitrosothiol-functionalized co-condensed silica particles. In some embodiments, provided are S-nitrosothiol-functionalized co-condensed silica particles.
