摘要：
Sol-gel inorganic porous particles can be formed with two set of pores with different average sizes. These inorganic porous particles are composed of an inorganic compound that provides an inorganic solid phase including an external particle surface. They also have a first set of pores wherein the pores have an average diameter of less than 100 nm and a second set of pores wherein the pores have an average diameter of at least 100 nm. The second set of pores contains stabilizing organic microgel particles. The first and second sets of pores are isolated from each other within the inorganic solid phase.
