Abstract

Lead ion is a well-known divalent metal ion because of its harm to the human body, and fluorescent tracer technique has been proven to be the most appropriate means to detect lead ion in human body. Many fluorescent probes have been proposed, and some have been applied successfully in lead detection. This paper reviews recent patents and research articles focusing on the design strategy of lead probe based on the molecular structure.

Keywords: Fluorescence, probes, metal ion detection, lead.
