Trapped oil: Candida antarctica lipase A is immobilized on oil-filled spherical silica nanoparticles with different silica shell structures through an anionic surfactant-induced self-assembly approach (see scheme) with ethanol as a cosolvent. The entrapped enzymes mostly retain their activities and exhibit recyclability and thermal and chemical stability, depending on the thickness and pore characteristics of the silica shells. TEOS=Tetraethoxyorthosilicate, APTES=3-aminopropyl triethoxysilane.
