In non-aqueous medium, bioimprinting could be used to enhance the enzymatic properties. In bioimprinting, the enzyme is combined with a substrate or its analog to form a complex similar to an enzyme–substrate complex in an aqueous solution, with theconformational change in the active site due to the induced fit. This change in conformation cannot be altered when the ligand is washed away in an essentially anhydrous organic solvent, owing to the rigid structure of the enzyme as a result of strong electrostatic interactions in the medium possessing low dielectric constants. Thus, the modified structure similar to ‘‘remembering’’ the structure of the ligand is frozen. As a result, the performanceof the enzyme is significantly improved due to the increase in the affinity between the enzyme and its substrate [37]. Improvement in the enzymatic properties after bioimprinting and interfacial activation in non-aqueous media has been described in numerous literatures in the recent decade, confirming that bioimprinting and interfacial activation are convenient and efficacious
strategies to improve the performance of lipases [38,39].
