Selective and sensitive recognition of Zn 2+ by a dansyl-derived peptide sensor

Key Points

• The aim is to create a peptide sensor capable of recognizing zinc ions selectively and sensitively.
• Designed a peptide sensor named Dansyl-HGHW (D1).
• Investigated its ability to selectively bind to Zn2+ ions.
• Achieved selective recognition of Zn2+ with high sensitivity.
