Benefiting from the strong interaction between the guanidinium group and the pTyr side-chain, the specific sensing of pTyr peptide was achieved by performing a simple logic operation based on PEI-PG-modified nanochannels when Ca2+ was introduced as an interferent. The excellent pTyr sensing capacity makes the nanochannels available for real-time monitoring of the pTyr process by c-Abl kinase on a peptide substrate, even under complicated conditions, and the proof-of-concept study of monitoring the kinase activity demonstrates its
