The aim of the study was to develop preparation methods of porous chitosan structures and to investigate their morphological properties as well as the kinetics of model substance release (salicylic acid). Chitosan scaffolds were generated using the liophylisation method and the systems obtained were saturated with hydroxyapatite and salicylic acid. Microscopic investigations (optical and electron microscopy) were carried out to examine the morphology of structures and water vapour sorption isotherms were determined to define the influence of hydroxyapatite on the system sorption ability. Additionally, the kinetic curve for the model substance release process (the process of the 1st order) was determined.
