METHOD FOR NANOPARTICLE COATING OF SURFACES

A nanoparticle coated hydrogel may be formed by a method of electrospraying nanoparticles on to a surface includes providing a drug and polymer combination in solvent to an inner capillary of a coaxial dual capillary spray nozzle. A coating with a drug that releases over time may be provided. Open a...

More Information
Summary:A nanoparticle coated hydrogel may be formed by a method of electrospraying nanoparticles on to a surface includes providing a drug and polymer combination in solvent to an inner capillary of a coaxial dual capillary spray nozzle. A coating with a drug that releases over time may be provided. Open and closed matrixes may be selectively formed to help modify time release periods.
