Özet
The development of nano and micromotors has revolutionized the field of nanotechnology, offering innovative solutions for applications in biomedical engineering, environmental monitoring, and chemical sensing. Among these nano/micromotors, graphene quantum dot (GQD)-based micromotors have gained significant attention due to their unique optical and electronic properties. This study presents the synthesis and characterization of novel graphene quantum dot-based gold-nickel (GQD-Au-Ni) micromotors. These micromotors were synthesized using an electrochemical template deposition process, allowing precise control over their composition and structure. The GQD-Au-Ni micromotors exhibit multifunctionality, employing fluorometric, magnetic, and electrochemical methods for the selective and sensitive detection of ferric ions (Fe³⁺), with a remarkable limit of detection (LOD). The study highlights the potential of these micromotors in environmental monitoring paving the way for future research into multifunctional micromotors for a wide range of applications. The findings underscore the promise of GQD-based systems in advancing sensor technology and addressing critical challenges in environmental and health monitoring.
