Its patented OptiLink platform enables high drug loading of small antibody fragments leading to enhanced formulation, tumour specificity, reduced side effects and high potency. In this TSB co-funded project, PhotoBiotics is exploring how the OptiLink platform can be used to target and reformulate an existing poorly soluble cancer chemotherapy drug - doxorubicin. The resulting drugs could be safer and easier to administer, with higher levels of potency due to their tumour specificity.</ns2:abstractText></ns2:project>
