| 摘要 |
A sprayable hydrogel wound dressing composed of an aqueous solution of neutralized Carbopol and silver hydrosol of silver nanoparticles electrolytically formed from silver metal without the use or inclusion of organic materials. The hydrogel is sprayed with a physical barrier sprayer system which separates the hydrogel from the propellant. The hydrogel is thixotropic/shear thinning so that the viscosity of the hydrogel is sufficient reduced in the sprayer to allow spray formation and regains sufficient viscosity to resist running when deposited on a vertical surface.
