Nanosized organically modified silica (NORM) particles are promising platforms for encapsulating/conjugating active agents for petitions in bioimaging, light activated therapies and drug delivery. Photodynamic therapy (PDT) is an encouraging and significant therapeutic technique in which light is used to activate photosensitizer molecules, that further reacts with molecular oxygen to produce highly reactive and cytotoxic singlet oxygen. Localized PDT can lead to selective killing of malicious cancer cells. Herein, we have synthesized zinc phthalocyanine (ZnPc) encapsulated NORM particles (ZnPc/NORM), in which ZnPc acts as the photosensitizer and NORM particles act as a carrier and also stabilizer of ZnPc. Further characterization of nanoparticles has been done by various techniques to study the morphology, structure and optical properties. ABMDMA dye was used to evaluate the photodynamic property of ZnPc/NORM particles. These nanoparticles have great potential for being a PDT agent as these nanoparticles significantly generate singlet oxygen on irradiation with laser light, along with some hyperthermia (rise in temperature). In vitro studies have been carried out using adenocarcinomic human alveolar basal epithelial (A549) cells to study the anticancer PDT efficacy of ZnPc/NORM.
