    Abstract: The present invention relates to a nanocomplex in which the fluorescence and reactive oxygen generation are activated by the action of a specific enzyme overexpressed in cancer cells, and more specifically, to a graphene oxide/biopolymer-photosensitizer nanocomplex for a cancer cell selective fluorescence image or photothermal treatment which is obtained by combining graphene oxide to a responsive binder. The graphene oxide/biopolymer-photosensitizer anocomplex according to the present invention selectively reacts to an enzyme expressed in the cancer cells and generates a strong fluorescence signal, and generates reactive oxygen species and heat. Therefore, the graphene oxide/biopolymer-photosensitizer anocomplex according to the present invention can be applied to not only the fluorescence image diagnosis but also the photodynamic/photothermal treatment of cancer.

    Abstract: The present invention relates to a redox-responsive polymer-photosensitizer conjugate containing disulfide linkers which include disulfide bonds capable of performing cancer cell selective fluorescence imaging or photodynamic therapy by activating fluorescence and reactive oxygen production using a reducing agent. The polymer-photosensitizer conjugate bonded by the disulfide linkers suppresses fluorescence and reactive oxygen production by energy transfer between photosensitizers bonded by the polymers outside the normal tissues and cancer cells, and expresses strong fluorescence signals and cytotoxicity while producing reactive oxygen species when disulfide bonds are cut by intracellular reducing agent after being targeted and accumulated in cancer tissue or cancer cells. Therefore, production of fluorescence and reactive oxygen is activated only when the conjugate is entered into the cancer cells so that side effects can be reduced and cancer selective fluorescence imaging and photodynamic therapy can be performed.
