Novel sandwich-structured electrochemiluminescence immunosensing platform via CdTe quantum dots-embedded mesoporous silica nanospheres as enhanced signal labels and Fe3O4@SiO2@PS nanocomposites as magnetic separable carriers

mSiO2/CdTe nanocomposites were chosen as enhanced ECL labels. Fe3O4@SiO2@PS nanocomposites were used as magnetic separable carriers. The detection of CEA proved the feasibility of the immunosensing platform.101
