<p>A method for encoding and identifying biological materials is disclosed. The method may include encoding and identifying plants from which controlled substances may be derived and other materials for which movement and distribution may need to be tracked. The biological material may be first encoded using DNA oligomers. A spray method or the use of an encoded substrate, both using these DNA oligomers for encoding the biological material, may be employed. The biological material, or a part of the biological material, may be first encoded by atomizing a solution containing DNA oligomers onto it and then dried by an appropriate method. Thereafter, the part of the encoded biological material, or the nitrocellulose substrate, may be dissolved with a buffer solution for extracting the DNA oligomers. Then, the dissolved solution may be used for generating a barcode by a suitable detection scheme.</p> |
