Abstract

The invention discloses a preparation method and application of a Zn<2+> probe cyclically usable in a pure water medium, belonging to the field of fluorescent probes. The invention provides the fluorescent probe which uses a terpyridine polymer as an acceptor molecule and is used for detection of Zn<2+> in the pure water medium, and the probe can be cyclically used 40 times at most. The probe has good capability in selecting and identifying Zn<2+> and is hardly influenced by other metal ions. The detection limit of the Zn<2+> probe to zinc ions in the pure water medium is 1*10<-6> mol / L. The Zn<2+> probe cyclically usable in the pure water medium can be used for detection of zinc ions in a biological system, analysis, detection and fluorescence imaging of zinc ions in living cells and living tissue of organisms, detection of zinc ions in lesion tissue in clinical medicine and detection of zinc ions in environmental waste water.

Description

technical field

[0001] The invention belongs to the field of fluorescent probes, in particular to a Zn that can be recycled in pure water medium 2+ Probe preparation methods and applications. Background technique

[0002] Zinc is one of the essential trace elements for the human body. It plays an important role in many fields of human life activities. For example, zinc can improve the immune function of the human body and achieve anti-aging effects; zinc can be used as a cofactor to regulate Protein and enzyme activity; trace amounts of zinc can strengthen memory and delay brain aging; in addition, zinc also has a neuroregulatory function. Zinc deficiency can cause nerve growth and development to be hindered, and it will cause sexual organ development retardation, manifested as prostate and seminal vesicle development Insufficiency, decreased spermatozoa, resulting in reduced sexual physiology. The analysis and determination of zinc ions is generally carried out by atomic ...
