A novel nanoparticles-quantum dots-based fluorescence sensor array has been developed for sensing proteins and cancer cells. In this study, six types of nanoparticles (NPs, including CuO, ZnO, Eu2O3, AuNPs, AgNPs, Au-Ag core-shell) conjugated with CdSe quantum dots (QDs) were used as sensing elements to create the multi-sensors of array. The fluorescence of quantum dots was efficiently quenched by...
