Surface-Retained Alginate Hydrogel Coating for Enamel Protection.

Langmuir : the ACS journal of surfaces and colloids · Cao D, Zhou Z, Song B · 2026-09-22

Researchers developed an alginate hydrogel coating that adheres to tooth enamel overnight using natural calcium ions, remaining stable for over 24 hours while preventing bacterial biofilm formation and reducing bacterial activity by 70–90% on model enamel surfaces.
