Cover Feature: Ultrabright Terbium Nanoparticles for FRET Biosensing and in Situ Imaging of Epidermal Growth Factor Receptors (Chem. Eur. J. 64/2020)

Novel trifunctional ligands enable simultaneous bioconjugation (e.g., to antibodies), attachment to nanoparticle surfaces, and photosensitization of Tb ions, affording ultrabright biofunctionalized Tb nanoparticles. These luminescent nanoparticle bioconjugates were successfully implemented in time‐gated FRET spectroscopy and luminescence microscopy for homogeneous in‐solution biosensing and live‐cell imaging of EGFR transmembrane receptors.
