Description
Ahmet Erdem and co-authors give seaweed-based wound gels a germ-killing surface without wrecking their sponge structure, in a 2026 study. Agarose cryogels suit wound care but are biologically inert, and harsh chemistry can collapse their pores. Their fix treats the finished gel: a quaternary ammonium compound is bonded onto the surface under alkaline conditions.
Tuning time, temperature, and gel strength produced two grades of modification, confirmed by surface analysis. Porosity actually rose while the pore network stayed intact. The stronger grade hit Escherichia coli and Staphylococcus aureus hardest and left human vein cells about eighty-eight percent viable in extract tests. The authors propose the non-leaching scaffolds for chronic wound dressings.
