To overcome the disadvantage that prior labels are readily falsified, a method of nucleic acid code analystic technique used in an invisible falseproof label of goods or items is disclosed, which belongs to the field of the code technique. A selected nucleic acid fragment (especially DNA fragment) is dissolved in a solution and applied to various solid supports, then attached on the support after being dried. As a falseproof label, it is labelled directly on various solid goods, items or packages and auxiliaries thereof. Nucleic acid can be also incorporated directly into liquid goods or various liquid supports to form an invisible falseproof label. The detection method is nucleic acid molecule hybridization probe assays or polyase chain reaction specific primer assays. |
