Researchers at the University of Washington have designed the first end-to-end molecular tagging system that enables rapid, on-demand encoding and decoding at scale. Instead of radio waves or printed lines, the tagging scheme relies on a set of distinct DNA strands called molecular bits, or “molbits” for short, that incorporate highly separable nanopore signals to ease later readout. The molbits are extremely tiny, making them ideal for tracking small items or flexible surfaces that aren’t suited to conventional tagging methods.
