The Effect of Silk on the Stabilization of Labile Enzyme Lipoxygenase

Advanced NanoBiomed Research, EarlyView.
Entrapping lipoxygenase within silk significantly extended its stability from under 24 h to 10 days. Variations in silk molecular weight and freeze‐drying conditions influenced silk properties and enzyme interactions. This stabilization is leveraged to develop a linoleic acid electrochemical biosensor, integrating lipoxygenase with horseradish ...
