209,210 To modify the surface hydrophilicity of upconversion NPs to provide stable aqueous colloidal dispersions, and obtain the ability to conjugate biomolecules and other ligands on the upconversion NPs, a common approach for researchers is to coat the upconversion NPs surface with a layer of MSNs

Mechanistically, CuCQ acts as an inhibitor of the CT-like activity of proteasome, leading to apoptotic death in MDA-MB-231 cells (Mao et al., 2009), indicating that it has selective antitumor activity
