  • Publication number: 20240118607
    Abstract: The inventive concept provides a substrate treating method. The substrate treating method includes pre-treating a substrate by cleaning the substrate; etching the substrate by supplying an etchant and heating a substrate supplied with the etchant; and post-treating the substrate after the etching the substrate, and wherein the pre-treating the substrate, the etching the substrate, and the post-treating the substrate are each performed in different chambers, a substrate on which the pre-treating the substrate is completed is transferred in a dry state to a chamber at which the etching the substrate is performed, and a substrate on which the etching the substrate is completed is transferred in a wetted state with a liquid to a chamber at which the post-treating the substrate is performed.

  • Patent number: 11617813
    Abstract: Provided is a method of manufacturing a hyaluronate-coated high-functional suture and a high-functional suture manufactured thereby, and more particularly to a method of manufacturing a high-functional suture and a high-functional suture manufactured thereby, wherein a suture for internal and external surgery derived from a conventional chemical synthetic material is coated with a hyaluronate as a biocompatible material, thus improving biocompatibility, functionality and ease of use. Upon application of the hyaluronate-coated suture of the invention to the human body, the hyaluronate applied on the surface of the suture is rapidly swollen by body fluids and can thus function as a lubricant, thus being convenient to use by a surgical doctor and reducing the pain of a patient and maximizing the functions of skin filling or skin regeneration in the body.
