    Article Title: Metal Ion-Peptide-Intermediated Ligand Transfer for Serum Detection of the Omicron Variant of SARS-Cov-2 in Echinococcosis Patients.
    Article Snippet: A method is developed to electrochemically induce target-specific covalent capturing of the spike protein of SARSCov-2, forming a covalent peptide−protein complex fit for working with such complicated clinical samples.. Specifically, peptidecoordinated copper ions can be electrochemically controlled to induce cross-linkage between certain amino acids on the peptide probe and the target protein.. Therefore, target specificity can be tuned electrochemically, realizing highly specific targeting of the omicron S protein or broader specificity toward all variants of the virus.
