Abstract

Polysiloxane based on N-2-hydroxy-1,1-di(hydroxymethyl)ethyl-N’-3-triethoxysilylpropylurea was synthesized. The polymer forms small nanoparticles and their associates in water. The latter can retain poorly soluble luminophore and hydrophobic gadolinium complex. The doped particles are capable of interacting with proteins. Aqueous suspensions based on non-toxic siloxane nanoparticles can be used for visualization of results of assays of biological objects (bioimaging) by fluorescence and magnetic resonance tomography.
