Abstract (en)

[origin: WO2013150193A1] The invention relates to microparticles and nanoparticles made up of hydrophobized polysaccharides and an alpha-cyclodextrine. Said microparticles and nanoparticles are obtained by means of self-combining in an aqueous medium. Said hydrophobized polysaccharide is obtained by grafting alkyl chains of fatty acids via an acylation reaction. Said microparticles and nanoparticles make up systems used to encapsulate substances of interest, in particular in the pharmaceutical field, and to target said substances for therapeutic purposes.
