Upcycling Industrial Lignin Into Cationic Hydrogels With Potential for Sustainable Plant Protection
ChemSusChem, Volume 19, Issue 20, 28 October 2026.Industrial lignin is upcycled into cationic lignin (CL) and embedded within chitosan–genipin (CH–GPN) hydrogels to form bioactive hydrogel networks with potential for antimicrobial plant protection. The CL‐embedded CH–GPN hydrogels retain porous, gel‐like properties and show enhanced in vitro inhibition of the plant pathogen Pseudomonas syringae.
