Abstract:
In recent years utilization of quantum dots for stem cells detection and clean energy production has received intensive attention. Graphene and its derivatives have been widely studied because of their effectiveness on electronical and optoelectronical devices, chemical sensors, nanocomposites, and energy storage. By use of metal nanoparticles, such as AuNPs, we can develop properties of graphene, and control them via shifting the absorption peak wavelength and increasing its biocompatibility. In this research, hybrid nanoparticles of gold-graphene as core-shell and conjugated by polymeric linkers containing amine or thiol functions are synthesized. Our purpose is stabilization the absorption peak in near IR wavelengths by changing the AuNPs size. Changes in optical properties as change in polymer chain length and size of nanoparticles, and also increase the biocompatibility of Graphene compounds in human body by different methods of conjugating will be studied. Finally an appropriate system for desired optical properties will be offered
