text-align:justify;text-justify:inter-ideograph">In nature, enzymes are efficiently immobilized
on the cell membranes through multiple physical and chemical interactions, which
confers the enzymes with well-retained hirarchical structures and high
activity/stabilities. Meanwhile, green plants convert carbon dioxide (CO2)
and water into carbohydrates and release energy through coupling enzymatic CO2
reduction and photocatalytic cofactor regeneration. Inspired by the above
phenomena and principles, our group has engaged in the bioinspired preparation
of microcapsule membranes and the immobilization of enzymes for over ten years.
Specifically, we developed the bioinspired methods for the preparation of multi-scale
microcapsule membranes, and elucidated their formation mechanisms. We also
analyzed the interactions between enzymes and microcapsule membranes, clarified
the stabilization mechanisms of microcapsule membranes toward enzymes, and
finally realized the enhancement of enzyme activity and stabilities. We further
extended the applications of microcapsule membranes for the construction of
multi-enzyme catalytic systems and photo-enzyme coupled catalytic systems. In
this presentation, we would like to report the recent research progresses in
the above aspects from the viewpoint of mesoscience.
