SURFACE PROPERTIES OF A LASER-TREATED BIOPOLYMER

Original language description

Structured surfaces allow the application of commonly used polymers to be extended into specialized fields. This paper describes the construction of surface structures on biopolymer poly(L-lactide) (PLLA), with a method combining krypton fluoride laser (KrF), excimer laser exposure and thermal annealing. PLLA is a commonly used substrate for medical purposes, such as implants and tissue matrices, but it still has a number of limitations, which can be eliminated with its modification. This work is focused on morphological studies and roughness measurements of a structured PLLA substrate using atomic-force microscopy (AFM) and chemical changes investigated with UV-Vis spectroscopy and X-ray photoelectron spectroscopy (XPS). Finally, the biocompatibility of the material was tested using a model cell line of mouse embryonic fibroblasts (NIH 3T3). Using the laser treatment in combination with thermal annealing, we prepared surface layers with various patterns dependent on the chosen input parameters.
