Mesoporous ZnS nanorattles: Programmed size selected access to encapsulated enzymes
A size selective nanorattle was formed by encapsulating soybean peroxidase (SBP) within a ZnS mesoporous hollow sphere. Once encapsulated within the mesoporous hollow sphere, the SBP remained active against molecules smaller than the 3 nm diameter of the mesopores in the shell wall, while molecules...
