NUS researchers Zhang Yong and John Ho have developed a tumor-targeting method that remotely conveys light for photodynamic treatment.
The tiny, wireless, implanted device delivers doses of light over a long period in a programmable and repeatable manner.
PDT is usually used on surface diseases because of low infiltration of light through organic tissue. This remote approach to light conveyance allows PDT to be used on the inner organs with fine control. The team believes that it could successfully treat brain and liver malignancies in the future, and allow therapies that could be tailored during the course of treatment.
