Abstract

Pour venir à bout des inconvénients que procurent les étiquettes déjà falsifiées, la présente invention propose une méthode à technique analytique de code d'acide nucléique utilisée dans une étiquette infalsifiable invisible de marchandises ou d'articles, qui appartient au domaine de la technique des codes. Un fragment d'acide nucléique sélectionné (spécialement un fragment d'ADN) dissous dans une solution est appliqué sur divers supports solides, puis fixé au support après avoir été séché. En tant qu'étiquette infalsifiable, il est directement étiqueté sur diverses marchandises solides, articles ou emballages et leurs accessoires. L'acide nucléique peut également être directement incorporé dans les marchandises liquides ou dans divers supports liquides pour former une étiquette infalsifiable invisible. La méthode de détection consiste en des dosages par sonde d'hybridation de molécule d'acide nucléique ou des dosages par amorces spécifiques de réaction en chaîne de polyase.
