A method for producing a composition of lipidic particles coated with a cross-linked surface mesh, the method comprising the steps of: (i) preparing lipidic particles comprising pharmaceutically acceptable lipids, (ii) binding hydrophilic polymer chains to the surface of the lipidic particles, and (iii) cross- linking the hydrophilic polymer chains to form the cross-linked surface mesh. Pharmaceutical compositions comprising surface modified lipidic particles prepared according to this method are also described. The lipidic particles resist fusion with red blood cells and platelets in vitro, and are amenable to further derivatization by targeting molecules for controlled release of component and contents, thus providing a new generation of drug carrier systems.
