報告摘要

Semiconducting molecules often have interesting optical properties suitable for biomedical applications. However, they typically have poor water solubilities and are thus often overlooked. In this talk, a summary will be given on how the solubility issue can be addressed by packaging the hydrophobic molecules into nanoparticles. In particular, a newly developed approach of using ice as a template for controlling self-assembly of molecules into nanoparticles will be introduced. Examples will then be given on applications of these nanoparticles for imaging, photodynamic therapy (PDT) and photothermal therapy (PTT).

報告摘要

Despite the broad clinical applications of platinum-based anticancer drugs including cisplatin, their side-effects and resistance issues have encouraged researchers to look for novel metal-based anticancer complexes. Non-traditional platinum compounds have been extensively studied and they hold the promise to be further developed as the next-generation platinum drugs. On the other hand, using nanomaterials to deliver cisplatin specifically into cancer cells has proven to be promising to increase the anticancer efficacy of cisplatin and has been a hot topic in the recent years. In this presentation, I will summarize the recent progress in my laboratory in 1) the design, synthesis, and biological evaluation of dual-targeting non-traditional platinum anticancer agents and 2) investigation on the action mechanism of metal-based anticancer agents. Examples of platinum constructs that promote the activation of p53 pathway and that have chemo-immunotherapy function will be given.
