Significant attenuation and overheating, caused by the absorption of the excitation band (980 nm) in water, are the major obstacles in the in vivo application of lanthanide-doped upconversion nanoparticles (UCNPs). Therefore, appropriately-structured Nd3+-doped UCNPs with 808 nm excitation could be a promising alternative. Herein, we developed core–shell–shell structured Nd3+-sensitized UCNPs as imaging...
Enhanced cellular uptake efficiency of nanoparticles is important for their biomedical applications, including photothermal therapy (PTT) for cancer. In this study, a one-pot method was used to construct a positively charged and magnet-responsive nanocomposite comprising reduced graphene oxide anchoring iron oxide (RGI) with a polyethylenimine (PEI) modification, to improve the efficiency of cell...
