Process Optimization for Coating of Acanthus Ilicifolius Extract on Silk Sutures.

This study investigates the optimization of process parameters for coating silk sutures with Acanthus ilicifolius leaf extract. The increasing awareness of surgical site infections is a critical concern associated with the use of sutures in medical procedure undertaking. Our study aimed to assess the impact of three crucial coating factors, namely extract content, temperature, and duration, on the mechanical and antibacterial characteristics of silk sutures braided together. Through Box–Behnken design, in conjunction with the response surface approach, we conducted a thorough analysis to refine the model. The result showed that extract concentration directly influences both antimicrobial activity and elongation, while temperature and time primarily affect tensile strength and bending stiffness. To achieve the maximum tensile strength, minimum breaking elongation, minimum bending stiffness, and lower friction, all while maintaining the important antimicrobial efficacy of the sutures, this study emphasizes the use of response surface methodology in optimizing coating parameters for A. ilicifolius leaf extract on silk sutures. The response models are developed on the complex relationships between these parameters and the properties of the sutures. [ABSTRACT FROM AUTHOR]
