A method for detecting nano- and micro-plastics in an aqueous sample suspected of being polluted with nano- or micro-plastics is provided. The method is based on interaction of the nano- and micro-plastics with hyaluronic acid functionalized with a luminescent or fluorescent dye. The luminescent or fluorescent dye is Rhodamine B or the metallorganic complex Ru(bpy).

Luminescent sensor for nano/microplastics

The present invention relates to silica nanoparticles comprising at least two dyes. Said dyes have a respective relationship of donor-acceptor couple in an energy transfer process and have a molar absorption coefficient &#x2267;10,000 Mcmfor the considered spectral region, a fluorescence quantum yield &#x2267;0.01, good overlap integral, according to the F&#xf6;rster theory, between said donor and said acceptor dye; said active compounds may be lipophilic or may present a functionality useful for the introduction of a trialkoxysilane moiety. The dyes provide an efficient energy transfer process. Said nanoparticles are useful as probes in the field of medicine, in particular therapy and diagnostics, more particularly in theranostics, and in the field of analytical chemistry.
