Our mission is to develop next-generation tools for better imaging and to develop more targeted, less toxic and more effective cancer therapies. Using cutting-edge technology and a highly collaborative approach, we are exploring the application of porphysomes, a non-toxic nanoparticle that can safely travel through our bloodstream, accumulate inside tumour cells and biodegrade within our bodies. For example, we are testing ways to use them to precisely deliver and activate treatment in tumours, enhance cancer immunotherapy methods, and increase the safety and effectiveness of phototherapies.
