Nanoengineering of inert polymers to develop functionalized sulfonated polymers to harness the power of Alternate complement system to stimulate and amplify cytotoxic potentials of classical and lectin based complement system Manufacturing functionalized sulfonated polymer to better penetrate tumor microenvironment, actively target various cancer antigens in conjunction with monoclonal antibodies in a safe way to inhibit host inflammatory reactions while maximizing cytotoxic potentials. The methods provide nanopolymers to safely maximize the cytotoxic potential of existing and evolving cancer therapies. Combining nanopolymers with existing and evolving cancer drugs to provide personalized cancer therapies.
