F209 (2005). Multifunctional nanospheres for cancer cell capturing.
Top left: TEM image of nanospheres embedded with both fluorescent CdSe/ZnS QDs and magnetic nano-g-Fe2O3. The inset is a SEM image of H2N-St-AAm nanospheres. Bottom left: HRTEM images of some CdSe/ZnS QDs embedded in H2N-St-AAm. Right: A cover picture showing the final trifunctional nanospheres constructed by conjugating folic acid to the surface of the bifunctional nanospheres and captured cancer cells specifically. [H.
