ABSTRACT:
Sensor particles comprise a silica-based core and at least one photoluminescent dye. The silica-based core may comprise a plurality of pores and the at least one photoluminescent dye may comprise a reference dye, insensitive to its environment and analytes and a sensor dye, sensitive to either or both of the foregoing. The sensor particles may be employed to sense unknown environmental conditions or analytes in biological or non-biological systems, in vitro or in vivo.
