Circularly polarized luminescence activity from new cationic water soluble Sm(iii) and Eu(iii) complexes is triggered by one- and two-photon absorption processes. The Eu(iii) complex is shown to be an efficient NIR-to-RED probe in cellulo.

While numerous transgenic mouse strains have been produced to model the formation of amyloid-β (Aβ) plaques in the brain, efficient methods for whole-brain 3D analysis of Aβ deposits are lacking. Moreover, standard immunohistochemistry performed o
