Recently, various second near-infrared window (NIR-II, 1000-1700 nm) fluorophores have been synthesized for in vivo imaging with nonradiation, high resolution, and low autofluorescence. However, most of the NIR-II fluorophores, especially inorganic nanoprobes, are mainly retained in the reticuloendothelial system (RES)
A selective, simple and environment-friendly type fluorescence sensing platform between upconversion nanoparticles (UCNPs) and melanin-like polymer utilizing the photoinduced electron-transfer (PET) mechanism was developed. The effective fluorescence quenching of UCNPs by melanin-like polymers could detect tyramine and tyrosinase (TYR) activity
Lanthanide-based upconversion nanoparticles can convert low-energy excitation to high-energy emission. The self-assembled upconversion nanoparticles with unique structures have considerable promise in sensors and optical devices due to intriguing properties. However, the assembly of isotropic nanocrystals into anisotropic structures is a
Lanthanide-doped upconversion nanoparticles with a suitable surface coating are appealing for biomedical applications. Because high-quality upconversion nanoparticles are typically prepared in an organic solvent and passivated by hydrophobic oleate ligands, a convenient and reliable method for the surface modification of
