A new polythiophene derivative-based fluorescent sensor for Co2+, Cu2+, Cd2+, and its complex with Cu2+ for sensing homocysteine and glutathione

A stable 3D Cd(ii) metal–organic framework for highly sensitive detection of Cu2+ions and nitroaromatic explosives

“…5 Both deciency and overload of copper may cause some types of severe diseases, for instance hematological manifestations, Alzheimer's, and Wilson's diseases. 6 On the other hand, with the development of chemical industry all over the world, some widely used chemicals such as nitroaromatic compounds (NACs) have become a highlight research focus in recent years due to their high toxicity to the environment and human health, especially due to their easy explosivity. Therefore, the development of convenient, cost effective Cu 2+ ions and NAC detecting methods is a very important issue.…”

Lysosome-Targeting Fluorescence Sensor for Sequential Detection and Imaging of Cu2+ and Homocysteine in Living Cells

“… 24 − 27 To date, however, only a few sensors can sequentially sense Cu 2+ and Hcy 18 , 28 − 38 that usually operated in a mixed medium of organic solvent and water 18 , 28 , 29 , 31 , 32 , 34 , 35 and suffer from the interference from other analytes ( Table S1 ). 28 − 32 , 34 , 36 , 37 Besides, there are rare sensors available for continuous imaging of Cu 2+ and Hcy in living cells. 18 Thus, it is still urgently needed to develop bifunctional fluorescence sensors for the simultaneous detection of Cu 2+ and Hcy with high sensitivity and selectivity in a prefect aqueous solution and living cells.…”

“…Fluorescence sensors are regarded as the most charming method to real-time monitor and track biological species through combining with the laser confocal imaging technology due to its simplicity, sensitivity, and high temporal and spatial resolution. , In recent decades, a mass of fluorescence sensors has been developed to identify Hcy from other amino acids, especially structurally similar mercaptoamino acids such as Cys and GSH − by taking advantage of distinctive redox property of Hcy − or nucleophilic reactions based on −SH and/or −NH 2 of Hcy. − To date, however, only a few sensors can sequentially sense Cu 2+ and Hcy ,− that usually operated in a mixed medium of organic solvent and water ,,,,,, and suffer from the interference from other analytes (Table S1). − ,,, Besides, there are rare sensors available for continuous imaging of Cu 2+ and Hcy in living cells .

Incorporating Three Chiral Channels into an In-MOF for Excellent Gas Absorption and Preliminary Cu2+ Ion Detection

“…The Cu 2+ ion, an essential trace element, plays vital roles in the growth of the human body as well as of plants and animals. However, an overload of Cu 2+ may burden the organs within the body and cause some types of severe diseases, including hypertension, coronary heart disease, arteriosclerosis, and the related copper metabolism disordered Wilson’s disease. − Therefore, enhancing the selectivity and sensitivity of rapid response sensing for Cu 2+ ions is currently receiving considerable attention.…”
