    Research interests

    • Multifunctional polymer nanoparticles for cancer –targeted drug delivery
    • Redox-sensitive polymer-based imaging agent for tumor hypoxia
    • Nucleic acid-based therapeutic delivery

    Research synopsis

    The primary aim of our research is to design and create novel polymeric materials which can selectively responds to the signals stemming from tumor microenvironments such as local pH change, enzyme overexpression or hypoxia. The bioresponsive polymeric materials can provide effective means to deliver small drugs, proteins, siRNA and/or DNA. We are currently working on redox-sensitive polymers that are subject to the bioreduction mediated by oxidoreductases under hypoxic conditions in cancer. Nanoparticles based on the redox-sensitive polymers are sought for cancer-targeted delivery of different drugs.
