Abstract

Objective(s): Nanomaterials are playing major roles in imaging by delivering large imaging payloads, yielding improved sensitivity. Nanoparticles have enabled significant advances in pre-clinical cancer research as drug delivery vectors. Inorganic nanoparticles such as CdO/GrO nanoparticles have novel optical properties that can be used to optimize the signal-to-background ratio. This paper reports on a novel processing route for preparation of CdO/GrO nanolayer and investigation of its optical properties for application in in vivo targeting and imaging.Materials and Methods: Nanostructures were synthesized by reacting cadmium acetate and graphene powder. The effects ofdifferent parameters such as power and time of irradiation were also studied. Finally, the efficiency of CdO/GrO nanostructures as an optical composite was investigated using photoluminescence spectrum irradiation. CdO/GrO nanostructures were characterized by means of X-ray diffraction (XRD), atomic force microscopy (AFM), scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) and photoluminescence (PL) spectroscopy.Results: According to SEM images, it was found that sublimation temperature had significant effect on morphology and layers. The spectrum shows an emission peak at 523 nm, indicating that CdO/GrO nanolayer can be used for in vivo imaging.Conclusion: The estimated optical band gap energy is an accepted value for application in in vivo imaging using a QD�CdO/GrO nanolayer.
