2024-10-31 Fabrication of Zinc-Tryptophan Nano assemblies for Antibacterial and Wound Healing Applications doi:10.57760/sciencedb.15786 en Wound healing is a complex process often hindered by factors including infection, oxidative stress, and inflammation, particularly in chronic wounds. Zinc (Zn) has therapeutic potential due to its antibacterial, antioxidant and anti-inflammatory properties. Similarly, the amino acid tryptophan (W) plays a crucial role in protein synthesis for tissue repair. Herein, we developed zinc-tryptophan (Zn-W) nanosheet assemblies with enhanced multifunctional properties, demonstrating a versatile biomedical application: antioxidant, antibacterial, antibiofilm and wound-healing. Detailed characterization studies were performed for the newly synthesized Zn-W nano assemblies. In vitro assays revealed potent antibacterial and antibiofilm activities against both gram-negative (E. coli) and gram-positive bacteria (B. subtilis), while antioxidant assays confirmed significant free radical scavenging ability. In vivo wound models showed that Zn-W treatment markedly accelerated tissue regeneration. These results highlight Zn-W nano assemblies as promising therapeutics for managing infected and chronic wounds, combining the benefits of Zn and W while overcoming their individual limitations Zinc-tryptophan nano assemblies; Biocompatibility; Antibacterial; Antioxidant; Wound Healing; Rat model DURBA BANERJEE PUBLIC https://creativecommons.org/licenses/by-nc/4.0/ dataset Science Data Bank
