My research focuses on nanotechnology and nanomaterials for cancer research. Our lab has recently discovered porphysomes, the first all-organic nanoparticles that enable tremendous opportunities for photonic based imaging and therapy. Porphysomes were reputed "Top 10 cancer breakthroughs in 2011" by Canadian Cancer Society. My current research focuses on the assessment of porphysomes in photothermal therapy. Porphysomes are novel intrinsic multifunctional nanovesicles that serve as potent photothermal therapeutic agents due to their unique photoacoustic and photothermal properties. In my previous projects, I have successfully produced and characterized porphysomes in terms of their physiochemical properties, and have demonstrated that porphysome-enabled photothermal therapy (PTT) can completely eradicate tumours in a xenograft model. Currently, this project is ongoing with extension to orthotopic prostate tumour models to investigate the photothermal therapeutic efficacy of porphysomes for focal laser therapy in prostate cancer. In future projects, I aim to improve the porphysome formulation to include targeting ligands via collaboration for tumour-specific accumulation, and therefore enhance the therapeutic specificity and the overall therapeutic value.
