Abstract
Electrochemical and spectroscopic studies demonstrated that the N-truncated amyloid β peptide Aβ5–9 (Arg-His-Asp-Ser-Gly-NH2) possessing histidine at position 2 (His-2) formed ternary complexes with copper(II) and phosphate anions or phosphate groups of biomolecules. The recognition ability of Cu(II)-Aβ5–9 toward phosphate species provided a new perspective on designing phosphate-selective molecular receptors.
