The capsular structure of liposomes is attractive for encapsulation of pharmaceuticals to develop nanoparticle-based drug delivery systems. Here unique liposomes which are modified with succinic acid on their surface arereviewed at a point of view of drug delivery carriers. The negatively charged carboxyl group of the succinic acid onthe surface of the liposomes contributes to facilitate the formation of the unilamellar liposomes which have superiorability to efficiently encapsulate the pharmaceuticals. Interestingly, we found that the liposomes modified with suc-cinic acid are highly distributed in the bone marrow through the intravenous injection. These characteristics of thesurface–modified liposomes with succinic acid would be applicable for the drug delivery system targeting bone mar-row.
