Described herein are compounds and methods useful in the detection of, e.g., Zn 2+ , in vitro and in vivo. The compounds include amino acids and peptides functionalized with a moiety that binds, e.g., Zn 2+ . The peptides may be further functionalized with a detectable moiety. The peptides may also comprise amino acid sequences known to localize extracellularly or in specific areas within a cell. |
