Conjugate of a photosensitiser and chitosan and uses thereof

摘要

The present invention relates to novel chitosan-based conjugates, e.g. nanocarriers, comprising a derivative of the biocompatible polymer chitosan conjugated to a photosensitising agent, and uses thereof in photochemical internalisation (PCI) and photodynamic therapy (PDT). The invention also relates to the use of the novel conjugates of the invention in treatment or prevention of diseases, particularly cancer, and for vaccination purposes.
