Abstract
Polymeric porous particles have a continuous solid phase and at least two different internal pores that are isolated from each other within the continuous phase. At least one set of discrete pores contains a marker material, and some instances, each set of discrete pores contain different pores marker materials that are isolated from each other. These marker materials are detectably different from each other. The porous particles can be spherical or non-spherical and can be used in any situation where the detectably different marker materials can be evaluated.
