Peroxidase-Like Activity of Green Synthesized Carbon Quantum Dots

This book chapter delves into the peroxidase-like activity of Carbon Quantum Dots (CQDs) synthesized through environmentally friendly methods. Green synthesis methods, such as hydrothermal and microwave-assisted techniques, are explored for their role in producing CQDs with unique catalytic properties. The investigation emphasizes the significance of sustainable nanomaterials, aligning their catalytic efficiency with eco-friendly practices. CQDs, known for biocompatibility, low toxicity, and tunable luminous properties, exhibit promising peroxidase-like activity. The study addresses the mechanistic insights behind CQDs’ catalytic behavior, examining surface functional groups, heteroatom doping, quantum confinement effects, and the role of defects. These factors contribute to the enzyme-mimicking capabilities of CQDs, paving the way for optimized applications in biosensing, environmental remediation, and beyond. The synthesis methods are scrutinized, highlighting recent advances in green approaches using natural precursors. The chapter synthesizes diverse research sources, offering a comprehensive understanding of green-synthesized CQDs’ peroxidase-like capabilities. From catalytic mechanisms to applications in cancer therapy and water purification, this chapter encapsulates the transformative potential of green-synthesized CQDs in science and technology.
