We report the synthesis of supported lipid bilayer (SLB)-coated radioluminescent nanoparticles (RLNPs) possessing a lanthanide-based core for low-dose X-ray activated photodynamic therapy (XPDT). Methylene blue (MB) photosensitizer molecules, incorporated within the SLB, are excited by energy transfer from europium, leading to an enhanced generation of re ...

Dye sensitization is a promising approach to enhance the luminescence of lanthanide-doped upconverting nanoparticles. However, the poor photostability of near-infrared dyes hampers their use in practical applications. To address this, commercial IR820 was modified for improved photostability and covalently bonded to amine-functionalized silica-coated LnUC ...
