Abstract	Magnetic optical sensor particles were prepared using a mini-emulsion solvent evaporation (MESE) technique. The resulting nanoparticles (NPs) have diameters around 100 nm and relatively narrow size distribution (PDI < 0.2). Incorporation of probes for oxygen or pH resulted in magnetic sensor particles for bioprocess monitoring and imaging applications. The MESE technique yields sensing NPs in higher quantities than obtained by a previously reported nanoprecipitation method, and the size of the NPs is smaller than that of particles made by spray-drying of sensor cocktails. Moreover, the technique is flexible in terms of polymers, solvents and indicators used in that it may be applied—at least in principle—to numerous combinations of two-phase systems.
