Dye aggregates give energy transfer a boost! Efficient energy transfer between organoboron and Rhodamine dyes are utilized to produce two-photon excitable polylactide nanoparticles, which exhibit high brightness and photostability. These ‘super-bright’ nanoparticles are particularly suited for imaging sensitive specimens such as live neuronal cells. Tissue imaging is also demonstrated, to show that such new imaging agents can find various applications for life sciences.
