Abstract
In this study, we have prepared tumor-targeted hydrophilic UCNPs by coating folate-modified amphiphilic SOC polymer on the surface of OA-UNCPs through hydrophobic interaction. The produced FASOC-UCNPs have excellent optical properties and good dispersibility in aqueous solution. TEM image and FTIR spectra confirm the successful surface modification of OA-UCNPs and folate-conjugation on the UCNPs. Folate-conjugated UCNPs possess active-targeting ability mediated by FR, compared with passive-targeted SOC-UCNP taken up by tumors via the EPR effect. Singlet oxygen production in cancer cells induced by FASOC-UCNP-ZnPc demonstrates the great potential of the nanocomplex as a novel PDT agent based on UCNPs.
