Solvatochromic dissociation of non-covalent fluorescent organic nanoparticles upon cell internalization†
Abstract
Amorphous red-emitting materials involving solvatochromic small molecules have been processed by the reprecipitation method as non-doped nanospheres characterized by a remarkably low polydispersity. Their mean diameter could simply be tuned by the concentration of the organic solution giving rise to time-stable dispersion of 85–200 nm-sized
