Activity, Recyclability, and Stability of Lipases Immobilized on Oil‐Filled Spherical Silica Nanoparticles with Different Silica Shell Structures
Abstract Candida antarctica lipase A was immobilized on spherical silica nanoparticles with oil‐filled core and oil‐induced mesoporous silica shell with different silica shell structures. The immobilization of enzymes was achieved by directly adding enzymes to the oil‐in‐water emulsion system under...
