Carcinoma cellular uptake, imaging, and targeting by RGD- and TAT-conjugated upconversion and/or magnetic nanoparticles

Original language description

We have developed monodisperse magnetic Fe3O4, upconversion NaYF4:Yb3+/Er3+, and dual paramagnetic/upconversion NaGdF4: Yb3+/Er3+ nanoparticles with tunable size by thermal decomposition of Fe(III) oleate and lanthanide chlorides in high-boiling organic solvents. Aminosilica and 4-pentynoic acid were then introduced on the particle surface to conjugate the cell adhesive and cell penetrating RGD and TAT peptides, respectively. Optionally, NaYF4:Yb3+/Er3+@SiO2-NH2 particles reacted with methoxyPEG succinimidyl ester to diminish uptake of the particles by the reticulo-endothelial system. Neural stem cell viability and labeling efficiency of the particles were determined. Al carboxyphthalocyanine was conjugated to NaYF4:Yb37Er3+@SiO2-PEG nanoparticles, which were intravenously administered in athymic nude mice with xenotransplanted human prostate carcinoma PC-3. After NIR photodynamic therapy, the tumor subsided and its volume approached to zero.
