The unique viscoelastic nature of H

The unique viscoelastic nature of HA along with
its biocompatibility and non-immunogenicity has
led to its use in a number of clinical applications,
including the supplementation of joint fluid in
arthritis (Neo et al., 1997; Barbucci et al., 2002;
Uthman et al., 2003; Medina et al., 2006), as a surgical aid in eye surgery, and to facilitate the healing
and regeneration of surgical wounds. More recently,
HA has been investigated as a drug delivery agent
for various administration routes, including ophthalmic, nasal, pulmonary, parenteral and topical
(Brown and Jones, 2005)
