PEEKplus subtractive nanotexturing on PEEK is antimicrobial and osseointegrating due to its adsorption of the key beneficial proteins, lubricin, mucin, casein, vitronectin and fibronectin, which make those benefits possible. 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.
PEEKplus provides the differentiable clinical benefits of antimicrobial and osseointegrating PEEK with no added clinical or technical risk.
PEEKplus subtractive nanotexturing removes less than 50 nanometers of material from the surface of an implantable device, which are on average 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. While at the same time, PEEKplus nanotexturing fully preserves all PEEK’s positive attributes.
