<p>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.</p> |
