Vallum’s in vitro studies have shown subtractive nanotexturing on polyethylene significantly reduces bacterial attachment and wear as compared to control polyethylene and correlates with the significantly increased adsorption of the beneficial proteins, lubricin, mucin and casein on nanotextured polyethylene as compared to control polyethylene. Adsorption is the adhesion of molecules from a liquid to a surface. This process creates a film of the adsorbate on the surface of the adsorbent. This process differs from absorption, in which a fluid permeates a solid.
NanoGlide subtractive nanotexturing removes less than 50 nanometers of material from the surface of a polyethylene component in a total joint replacement. Since polyethylene components in total joint replacements are millions of nanometers thick, this imperceptible topographical change has no effect on dimensions, no effect on mechanical strength, no effect on design and no effect on chemical composition. ANAB nanotexturing fully preserves all of polyethylene’s positive attributes while improving the antimicrobial and wear resistant properties of polyethylene.
