Fingerprinting proteins with force

What if we could identify proteins as easily as we can sequence DNA and RNA? Perhaps soon we will, thanks to new DNA Nanoswitch Calipers. DNA Calipers create a unique 'fingerprint' for peptides (the building blocks of proteins) by repeatedly applying force to them to generate a series of distance measurements for each peptide. This innovation opens up a new avenue for pursuing the goal of single-cell proteomics, and enables potentially life-saving discoveries in human health and disease.
