Abstract: The present disclosure relates to a nanoparticle complex that is taken into cells to be used for the treatment of diseases, and a method of manufacturing the same using a top-down process. In the top-down process, surfaces of nanoparticles are modified with a lipid-based material having high stability and excellent biocompatibility, thereby improving endocytosis efficiency. A lipid structure having a tube shape is bonded to a portion of the surface of the nanoparticle, so that the nanoparticle complex undergoes endocytosis, directly penetrates a cell membrane, and is effectively taken into spheroid-type tumor cells. The lipid structure is not directly attached to the nanoparticles, lipid-based lipidomes (such as bubbles and liposomes) are bonded to the nanoparticles, and mechanical force is applied thereto to thus crush the lipidomes, so that the lipid structure is formed on the surface of the nanoparticle.
Abstract: A method of synthesizing silymarin-loaded collagen collagen nanoparticles can include dissolving silymarin in an alcohol to provide a solution, mixing the solution with acetic acid to provide an acetic acid mixture, and adding the glutaraldehyde to the mixture to provide silymarin nanoparticles. The silymarin nanoparticles can be dissolved in a further alcohol and mixed for a period of time to provide a silymarin nanoparticle mixture. Then, the silymarin nanoparticles can be mixed with collagen nanoparticles to provide a silymarin/collagen mixture. Glutaraldehyde can be added to the collagen mixture to provide the nanocomposite formulation.

Abstract: This invention describes ways of obtaining nano-particulated adjuvants formed by different synthetic variants of GM3 ganglioside. Depending on the fine structure of the fatty acid in the ceramide of the synthetic GM3, said adjuvants are able to stimulate specifically and in a specialized way the humoral or cellular immune response against accompanying antigens. Particularly, this invention provides immunogenic vaccine compositions that comprise peptides, polypeptides or proteins and the aforementioned nanoparticles, which are formed through the dispersion of hydrophobic proteins of the outer membrane complex (OMC) of Neisseria meningitidis in solutions containing fully synthetic variants of the GM3 ganglioside.
