Development of magnetic luminescent core/shell nanocomplex particles with fluorescence using Rhodamine 6G

► A simple method was developed to synthesize Co-B/SiO2/dye/SiO2 composite particles. ► The magnetic particle shows that highly luminescent and core/shell particles are formed. ► Such core/shell particles can be easily suspended in water. ► The magnetic particles could detect fluorescence for the application of biosensor.
