Barcoding of physical objects with molecular tags holds an advantage over traditional paper or electronic barcodes in that they are discreet, durable, and difficult to falsify. Here, we developed a DNA tagging system that labels objects to verify their authenticity and trace their origin. We chose DNA as our tagging medium due to its information storage capacity and chemical stability, allowing us to generate a wide variety of unique barcode sequences that can be read by Oxford Nanopore’s MinION sequencing device. The MinION contains an array of thousands of nanopore sensors that are capable of sequencing single strands of DNA. The nanopore sequencing process creates distinct disruptions in the ionic current through the sensors that are indicative of the DNA sequence. However, the DNA basecalling software that processes the raw ionic current is computationally expensive, making it impractical when our goal is to quickly “scan” and identify a tagged sample. Because of this, we designed our barcode sequences to generate unique current patterns that are identified using a simple classification algorithm as opposed to arduous basecalling. So far, we have synthesized and classified a set of 96 barcodes that can be indiscriminately combined to create multi-bit tags. In a given tag, each bit is defined by the presence or absence of a particular barcode, and in practice, we have assembled and read up to 16-bits. We have also explored increasing bit capacity by independently varying barcode lengths, which adds another dimension to the barcode space. We also tested the durability of our barcodes by drying them onto filter paper and sequencing them 24 hours later, proving that our barcodes could survive in a dehydrated state. Future experiments will aim to lengthen this duration and expose the barcodes to different environments, in order to better simulate intended tagging conditions.
