Engineering lignin-based antimicrobials: Experimental foundations and data-driven optimization.

Lignin-based antimicrobial materials are increasingly optimized using mechanism-informed, application-specific, data-driven design, integrating experimental foundations with machine learning and global optimization approaches.

• Why it matters: The field needs clearer links between lignin chemistry and antimicrobial performance, plus better tools to predict and optimize activity across diverse material formats and applications.
• What they did: The work reviews strategies including depolymerization, fractionation, and chemical modification, and summarizes recent lignin-based hydrogels, films, coatings, nanomaterials, and polymer composites alongside emerging computational methods.
• The result: The review frames how modeling and optimization can bridge experimental and computational toolsets to guide design and improvement of lignin-based antimicrobials.
