Colon cancer is a major cause of death worldwide and it is expected to rise in the coming years. The development of nanoscale delivery of active substances represents an exciting and new approach to cancer immunoprophylaxis. General aim of the project would be to conjugate an immunogenic antigen to gold nanoparticles in order to promote major histocompatibility complex – involving antigen processing by antigen presenting cells. Tailored pharmaceutical formulation of by a specially designed capsule is going to be used, in order to offer optimal intestinal delivery of nano-bio cellular vaccine.
