Abstract: PURPOSE: A method for preparing silica nanoparticles imparting thermal stability and mechanical strength by encapsulating aromatic oil with silica. CONSTITUTION: A method for preparing silica nanoparticles comprises the steps of: (i) forming an emulsion solution by adding surfactant, cosurfactant and aromatic oil to water; and (ii) adding a silica precursor to an emulsion solution to obtain silica nanoparticles. The surfactant is added in the amount of 1-4 weight% based on water. The cosurfactant is added in the amount of 1-10 volume % based on water.

Abstract: PURPOSE: A surgical mesh and a method for manufacturing the mesh are provided to obtain an operation convenience by maintaining an initial strength and a rigidity of a conventional polypropylene surgical mesh, to minimize inflammation caused by neophobia after the operation, and obtain excellent biocompatibility by helping a fast growth of a cell. CONSTITUTION: A surgical mesh comprises: a mesh main body; and a coating layer which is coated on the surface of the mesh main body and includes a bioactive substance. The coating layer more includes an adhesive material. The adhesive material is a biodegradable polymer. The bioactive substance is an anti-inflammatory agent, an antioxidant or a mixture of the anti-inflammatory agent and the antioxidant. The anti-inflammatory agent is dexamethasone, prednisolone, aspirin, ibuprofen, indomethacin or naproxen.
