A Facile, Two-step Synthesis and Characterization of Fe3O4-Lcysteine- Graphene Quantum Dots as a Multifunctional Nanocomposite, M.Sc. Thesis Sharif University of Technology ; Madah Hosseini, Hamid Reza (Supervisor)
Abstract
In this research, a facile, two-step synthesis was reported for 34-LCysteine- nanocomposites. The first step comprises the preparation of LCysteine functionalized magnetic nanoparticles (MNPs) core-shell structures via co-precipitation method. In the second step, graphene quantum dots (GQDs), which were synthesized by citric acid carbonization, added to the functionalized MNPs and finally refluxed at the appropriate time and temperature. LCysteine as a biocompatible, natural amino acid were used to link MNPs with GQDs. This nanocomposite was characterized by various techniques. XRD and FT-IR were used to investigate the formation of MNPs and LCysteine existence on the MNPs surface. XPS...
