title: Sub-ppt detection limits for copper ions with Gly-Gly-His modified electrodes.
abstract: An electrochemical metal ion sensor has been developed with a detection limit of less than 0.2 ppt by the covalent attachment of the tripeptide Gly-Gly-His as a recognition element to a 3-mercaptopropionic acid modified gold electrode.
