Y. Wang and F. Caruso Nanoporous Protein Particles Through Templating Mesoporous Silica Spheres Advanced Materials 18
Sequential assembly of protein and polyelectrolyte in mesoporous silica (MS) spheres leads to the formation of nanoporous protein particles (NPPs); the MS templates are removed after the fabrication process (see figure). The NPPs based on catalase show excellent biological activity, with up to 57 % of the activity retained. This strategy offers a novel and effective method of preparing bioactive NPPs of diverse composition, particle size, and shape.
