The purpose of this work is to develop long-term stable hydrogel materials (freeze-dried films and injectable hydrogels) enriched with phages. Both developed materials proved to be biocompatible and to have sufficient transparency, swelling, and retention behavior and appropriate mechanical properties such as elasticity (up to 120 – 140 % from original size in the hydrated state), easy handling of the film, and optimal injectability (thixotropic character). Phage-enriched GK-hydrogels biostability was tested in three months using the double agar method, which proved phage activity and antibacterial properties against MRSA 1137. These tests proved the biostability of the injectable hydrogel after three months of experiments where the phage reached a concentration above 1·108 PFU/ml. Phage visualization in the hydrogel matrix was performed using fluorescent microscopy with labeled phages and GK to determine if they were present in the hydrogel matrix. Based on the results, we can conclude that GK-based hydrogels are a suitable carrier for phages even for long-term storage, treat S. aureus-infected chronic wounds, and support the healing process of infected wounds.
