A multifunctional β-CD-modified Fe3O4@ZnO:Er3 +,Yb3 + nanocarrier for antitumor drug delivery and microwave-triggered drug release

We functionalized a multifunctional core-shell Fe3O4@ZnO:Er3 +,Yb3 + nanocarriers by adding β-cyclodextrin, which is capable of carrying drug molecules and triggered release of the drug by microwave treatment.
