Graphene Functionalization with Amines and Decorated with Metallic Nanoparticles for Antimicrobial Properties
2017
Overview
This master's thesis presents an advanced study on the functionalization of graphene with amines and metallic nanoparticles to enhance its antimicrobial properties, within the field of applied chemistry and nanoscience. Researcher Osama Abdelsattar aims to develop hybrid nanomaterials with high biological activity for potential medical and environmental applications, such as surface sterilization and water purification. The study involved preparing graphene samples functionalized with amine groups and subsequently decorated with silver, copper, and gold nanoparticles using wet chemical synthesis and controlled deposition techniques. The resulting composites were characterized using XRD, FTIR, SEM, and TEM analyses to determine their crystalline structure and surface morphology. Findings revealed that amine functionalization improved the homogeneous distribution of nanoparticles on the graphene surface, increasing surface reactivity and significantly enhancing antibacterial and antifungal activity. Biological assays demonstrated strong inhibition of E. coli and Staphylococcus aureus compared with free nanoparticles, confirming the synergistic effect of the graphene-based hybrid system. The researcher concludes that amine-modified graphene combined with metallic nanoparticles represents a promising approach for developing antimicrobial materials applicable in medical devices, filtration membranes, and protective coatings. The study recommends further exploration of other bioactive molecules to optimize performance for industrial and environmental uses. Abstract Written by Dar AlMandumh, 2025, Using AI.
