Abstract: A method for the preparation of a glucose polymer having an ion-exchanging ability comprises the steps of drying a mixed aqueous solution containing a raw glucose polymer and a polyvalent carboxylic acid to thus form a uniform powdery mixture and then subjecting the powdery mixture to a heat treatment. The method of the present invention can ensure the achievement of a high reaction efficiency, is economically advantageous since it never requires the use of any expensive catalyst and does not require the use of any complicated step for the removal of impurities. The glucose polymer prepared by the method of the present invention is biodegradable and can be used in, for instance, various foods and/or builders.

Abstract: The present invention is directed to particulate drug carriers, such as vesicles, formed from polysaccharide derivatives. A polysaccharide bearing at least one non-ionic hydrophilic group attached to an individual monosaccharide unit is hydrophobised to form a derivative bearing at least one long chain alkyl residue. Particle formation is then induced in the presence of cholesterol. The particles are suited for entrapment or conjugation of pharmaceutically active ingredients.
