3D single-molecule tracking revealed that the translational diffusion of guest dyes in poly(2-hydroxyethyl acrylate) thin films on glass substrates was confined in a horizontal layer at a distance longer than 300-700 nm from the surface of the substrate.
Shining nanosil: Fluorescent trimethoxysilanes were prepared by the hydrosilylation of N‐allyl perylene tetracarboxylic diimides and used for the covalent grafting of silica and silicananoparticles (see picture). The fluorescent chromophores operate independently at the surface of these particles.
