  • NANOCOMPOSITES OF NITROGEN-DOPED GRAPHENE OXIDE AND MANGANESE OXIDE FOR PHOTODYNAMIC THERAPY AND MAGNETIC RESONANCE IMAGING
    Publication number: 20230256116
    Abstract: The present invention relates to a NDG-Mn3O4 nanocomposite comprising a nitrogen doped graphene (NDG) and Mn3O4 nanoparticles. The NDG-Mn3O4 nanocomposite is useful in bimodal performance including photodynamic therapy (PDT) and magnetic resonance imaging (MRI). The NDG-Mn3O4 nanocomposites of the present invention caused significant cell death under laser irradiation, while control and Mn3O4 nanoparticles showed negligible cell death.

  • HYBRID NANOPARTICLES COMPRISING MANGANESE OXIDE AND HIGHLY REDUCED GRAPHENE OXIDE FOR THERANOSTIC APPLICATIONS
    Publication number: 20220339300
    Abstract: The present disclosure provides HRG-Mn3O4 hybrid nanoparticles. The HRG-Mn3O4 hybrid nanoparticles do not pose any cytotoxicity at normal physiological conditions and therefore they are nontoxic and biocompatible at physiological conditions. The HRG-Mn3O4 hybrid nanoparticles under exposure of laser light cause massive cellular damage indicating their potential use for photodynamic therapy of cancer. The HRG-Mn3O4 hybrid nanoparticles enhance the magnetic resonance signals from cancer cells and exhibit excellent MRI contrast property for tumor imaging and are therefore useful contrast agent.
