A. Bioadhesive Examples

The majority of work using bioadhesives in drug delivery has been with a small number of water-soluble and water-insoluble polymers. Water-soluble polymers are not cross-linked, whereas water-insoluble polymers are often swellable networks joined by cross-linking agents. Bioadhesives can be natural or synthetic in origin, but in drug delivery systems, nonbiological macromolecules or hydrocolloid materials are often used. Some examples of bioadhesives are given in Table 1.
