New fluorescent probe for Zn²⁺ imaging in living cells and plants

Abstract

The 8-aminoquinoline based probe exhibited high selectivity and sensitivity toward Zn2+ under a physiological pH. Moreover, its high cell permeability grants the access to employ L1 as Zn(ii) detector in both human cells and plant tissues.

A novel and simple solvent-dependent fluorescent probe based on a click generated 8-aminoquinoline–steroid conjugate for multi-detection of Cu(ii), oxalate and pyrophosphate

“…42 And 8-aminoquinoline and its derivatives are well-known excellent building blocks for constructing highly selective uorescent sensors of transition metal cations. 36,[43][44][45][46] Meanwhile, the bridging 1,2,3-triazole group was introduced via click chemistry in order to offer not only a straightforward strategy for the linkage of various functionalities, but also a potential binding site for both metal ions and anions, 47,48 which is very benecial for multi-target analysis.…”

Biosorption of Zn2+, Ni2+and Co2+from water samples onto Yarrowia lipolytica ISF7 using a response surface methodology, and analyzed by inductively coupled plasma optical emission spectrometry (ICP-OES)

“…[1][2][3][4] Heavy metal ions (antimony, arsenic, beryllium, cadmium, chromium, copper, lead, mercury, nickel, selenium, silver, thallium and zinc) are non-biodegradable, toxic and carcinogenic compound harmful to organisms even at very low concentrations and lead to the generation of hazards and injury to public health. [5][6][7][8] Ni 2+ ions are a major concern because of their extensive application in developing countries and their potential pollution effects. This metal is released into the environment by many processes such as electroplating, leather tanning, wood preservation, pulp processing, steel manufacturing, plastic pigmentation, mining and metallurgical processes.…”
