Caption: Fluorescence of a polymer molecule. In this study of a melting gel substance, polymer molecules within the gel have been marked with a fluorescent chemical. Laser beams are used to illuminate this marked polymer molecule to trace its movements and behaviour. At centre, yellow light corresponds to the illuminated polymer molecule. Photo-bleaching by the lasers causes unmarked polymer molecules to colour blue. This is part of the French physicist De Gennes's work at College de France et Ecole de Physique-Chimie in Paris. De Gennes has studied polymer molecules of glue, paint, plastics etc, to better understand these industrial gels. De Gennes received the Nobel Prize for physics in 1991.
