Protein adsorption on spark plasma sintered 2d-, 3d- and lamellar type mesoporous silicate compacts.

The preparation of lamellar type mesoporous silica (MPS) compact through the spark plasma sintering (SPS) and the adsorption/desorption of protein onto MPS compact are reported to be compared with those onto 2d-hexagonal and 3d-cubic type MPS compacts. A lamellar-type MPS powder (MPS-la) was prepared using triblock copolymer, PEOPPOPEO, and was compacted in a carbon die and heated at 500°C for 5 min under uniaxial pressure. The products are referred to as MPS-la-500.
