Synthesis and Characterization of Curcumin-Lysine Carbon Dots

İngilizce (OpenAlex)

Antibacterial materials are designed to inhibit or kill bacterial growth, making them essential in applications where hygiene and infection control are critical, such as wound care and medical devices. Carbon dots (CDs) are nanoscale materials with unique optical properties, chemical stability, biocompatibility, and ease of synthesis and functionalization. The properties of CDs are primarily determined by the precursors used for synthesis. In this study, we synthesized CDs from curcumin and L-lysine using a furnace-based method. Structural and optical characterization confirmed successful carbonization. The synthesized CDs exhibited mild antibacterial activity with an average inhibition zone of approximately 0.5 mm compared to the blank disc against the common wound pathogen, Staphylococcus aureus. They also supported viability above 80% up to 1mg/ml concentration. These findings indicate the potential of these carbon dots as biocompatible antibacterial agents for wound healing.
