Core-shell nanocarriers with ZnO quantum dots-conjugated Au nanoparticle for tumor-targeted drug delivery

► We synthesized core-shell structured multifunctional nanocarriers. ► Nanocarriers had great potential as tumor-targeted drug delivery nanocarrier. ► Nanocarriers had certain antitumor activities. ► Tumor cells could be killed by the cooperation of nanocarriers and drugs.
