Summary:	Title screen Poly(lactic) acid (PLA) is biodegradable polymer that nowadays is being used as a material for various medical applications. However, it has several drawbacks like low biological activity and absence of radiopacity. Iodine and iodine-containing compounds are well-known for their antibacterial and radiopaque properties. In order to improve PLA-based biomaterials properties we developed new surface modification method based on “solvent/non-solvent” treatment with subsequent entrapment of iodine either from its vapour or solutions. It was shown that developed technique allows us to create an iodine layer on PLA-based materials surface with estimated amount of iodine from 10-9 to 10-8 g/cm2 . Stability of such layer was also investigated and it was shown that it is stable enough to be used for medical applications requiring long-term iodine release into water medium.
