A particle (1) for tagging a liquid. The particle comprises a nucleic acid tag; a carrier nucleic acid; and a linear polymer. The linear polymer has a backbone comprising amido and tertiary amino groups arranged regularly on the backbone. The nucleic acid tag and the carrier nucleic acid have different sequences. The particle comprises at least ten times more carrier nucleic acid than nucleic acid tag. Use of particles for marking materials in which the particles comprise the said linear polymer and a nucleic acid.
La présente invention concerne une particule (1) destinée à marquer un liquide. La particule comprend un marqueur d'acide nucléique; un acide nucléique porteur; et un polymère linéaire. Le polymère linéaire a un squelette comprenant des groupes amidiques et amino tertiaires disposés régulièrement sur le squelette. Le marqueur d'acide nucléique et l'acide nucléique porteur ont des séquences différentes. La particule comprend au moins dix fois plus d'acide nucléique porteur que de marqueur d'acide nucléique.
