The aim of the project will be to develop microparticles and nanofibre materials with phages as antimicrobial agents.The phages will be ideally released in a controlled manner and the maximum efficacy will be maintained. The materials will have wider applications in medicine, food, industry, agriculture in biotechnology etc. In cooperation between FAGOFARMA, experienced in the development of phage preparations, VŠCHT and ČVUT, who are experts in field of nanomaterials, microparticles and encapsulation of functional substances, methods of preparation of materials will be optimized. Challenges such as the surface distribution of phages in material, its sterilization without affecting the active substance and the structure of the material will have to be solved for implementation in practice.
