  • Patent number: 11697762
    Abstract: A method of fabricating the organic-inorganic hybrid coating layer includes: preparing a gel mixture including an organic precursor and colloidal silica particles; preparing a first mixed solution by heating the gel mixture; preparing a second mixed solution by adding quantum dots to the first mixed solution; and coating the second mixed solution on a substrate and irradiating light thereon to form a polymer matrix in which the organic precursor and the colloidal silica particles are crosslinked, and preparing a coating layer in which the quantum dots are dispersed in the polymer matrix, wherein the organic precursor may include at least one of dipentaerythritol pentaacrylate (DPPA) or dipentaerythritol hexaacrylate (DPHA).

  • Publication number: 20230172843
    Abstract: Disclosed is a method of preparing a pH-sensitive controlled-release emulsion hydrogel using chitosan and pectin. More particularly, disclosed is a method of preparing a pH-sensitive controlled-release emulsion hydrogel that is capable of entrapping various substances to be encapsulated and is stable in gastrointestinal conditions, but upon exposure to neutral pH after passing through the stomach, releases the entrapped emulsion in response to the pH.

  • Patent number: 10660853
    Abstract: Disclosed are a method of preparing liposomes using a mixed solvent of ethyl acetate and n-hexane for dissolving phospholipids, and a method of preparing a liposome frozen powder by putting a container including liposomes in a container filled with isopropyl alcohol, ethanol and/or methanol, followed by lyophilization, which methods are useful in food industry for no use of toxic chloroform. Disclosed also is adding the produced container including liposomes to a container filled with isopropyl alcohol, ethanol and/or methanol, followed by lyophilization, thus advantageously preventing deterioration in stability of liposome particles, as well as being almost completely returned to the original state.
