Polarization microscopy was used for evaluation of kinetics of diclofenac sorption in three different wound dressing materials. The sorption kinetics can be evaluated by radii change and intensity of the light traveling through the fiber. The most frequently used host materials for drugs in wound dressings are alginate, polyesters such as polyethylene terephthalate, and viscose. We studied sorption of diclofenac as an example drug. Effective, but rather simple in vitro simulation of diclofenac sorption gives insight into the applicability of the mentioned materials for development of wound healing materials.
