title: Attachment of hyaluronic acid to polypropylene, polystyrene, and polytetrafluoroethylene.
abstract: Surfaces of polypropylene (PP), polystyrene (PS) and polytetrafluoroethylene (PTFE) were activated with radio frequency plasmas Ar and NH3 to aminate the polymer surface and were subsequently reacted with hyaluronic acid (HA) in one of the three different attachment schemes. Results show that ammonia plasma treated polymers were more reactive toward HA attachment. The three chemistry schemes consisted of two distinct approaches: (1) direct attachment of the HA to the aminated surface, and (2) extending the reactive group away from the surface with succinic anhydride and then reacting the newly formed carboxylic acid group with an adipic dihydrazide modified HA (HA-ADH). The latter scheme proved to be more effective, suggesting that steric effects were involved with the reactivity of the HA with surface groups. These HA-coated polymers are a candidate for cell attachment and growth.
