Modification of NaYF4:Yb3+,Er3+ Up-Converting Nanoparticles with Phospholipid Coating for Cell Imaging
Abstract
UCNPs are widely studied due to possible applications in biomedical imaging and therapy. In this study we investigated NaYF4:Yb3+,Er3+ UCNPs as a potential nanomaterial for biomedical applications. We showed that UCNPs are photostable and do not degrade under prolonged exposure to NIR irradiation. Several surface modifications were tested using DOPC and PEG-DOPE phospholipids. Highest solubility in water was achieved when UCNPs were coated with the mixture of these lipids. NIH3T3 cells accumulated DOPC:PEG-DOPE-UCNPs and showed little to none viability decrease. UCNPs show potential as fluorescent nanomaterial but this relatively new field requires further research to utilize upconverting nanoparticles in medical diagnostics and therapy.
