A nanopore framework has been developed to reveal the crosstalk effect on the renin–angiotensin system. By reading the single-amino-acid differences in angiotensin peptides with high accuracy and high efficiency, the selective inhibition of angiotensin-converting enzyme by angiotensin-converting enzyme 2 was revealed. This activity was shown to be suppressed by the spike protein of SARS-CoV-2.
