Methodologies have been developed and certain recognizing substances and crosslinking reagents have been identified to modify liposomes. Crosslinking reagents link residues on the liposomal surface to the residues offered by certain recognizing substances. The crosslinking reagents include glutaraldehyde (GAD) and a water soluble carbodiimide, preferably, 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC). The recognizing substances include gelatin, collagen, and hyaluronic acid (HA). Following these methodologies, recognizing substances can be utilized as an adhesive or glue to attach the liposomes onto a target area. These "bioadhesive" liposomes offer potential advantages as a microscopic drug delivery system. |
