“Dark” organic triplet states typically require visible light to activate via singlet-triplet intersystem crossing. In this issue of Chem, Deng and co-workers report a new near-infrared photosensitization strategy using lanthanide-doped nanoparticles directly the dark photosensitizers, significantly reducing power requirement irradiance. The current photosensitizers used in photodynamic therapy...

Abstract Splitting of the effective Rabi frequencies for plasmonic fields when interaction occurs between semiconductor quantum dot and three metallic nanospheres in presence electromagnetic is examined. We study theoretically role dipole–dipole interactions creating many Multipoles. Then, we split into parts according to quantitative Multipoles fields. The density matrix equations are derived ...

Labrafil M2125-CS is a non-ionic surfactant component widely used for improving the solubilization of poor water-soluble drugs and as lipid-based nanosystem formulation. The aim this research work was to evaluate in depth stability nanosystems when exposed at several experimental conditions, such temperature- pH-variations, during specific storage process—lyophilization. Dynamic light scatterin...
