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.

L'invention concerne un revêtement d'hydrogel nanoparticulaire qui peut être formé par un procédé d'électropulvérisation de nanoparticules sur une surface, comprenant la fourniture d'une combinaison de médicament et de polymère dans un solvant à un tube capillaire d'une buse de pulvérisation coaxiale à deux tubes capillaires. Ceci permet d'obtenir un revêtement comprenant un médicament qui se libère avec le temps. Des matrices ouvertes et fermées peuvent être formées sélectivement pour aider à modifier les périodes de libération contrôlée.
