Highly selective and sensitive fluorometric probe for Cd2+ ions based on 4-(quinolin-2-ylmethylene)aminoanisole Schiff base

Yuwei Dong et al.

Summary: A reversible and easily assembled fluorometric probe QMAA was developed for the selective and sensitive detection of cadmium ion in DMF solution with PBS buffer. The strong fluorescence response of QMAA to Cd2+ was attributed to the formation of the QMAA-CdCl2 complex, inhibiting C=N isomerisation and PET. The detection limit of QMAA for Cd2+ was lower than the WHO-defined acceptable limit in drinking water.

An efficient PET-based probe for detection and discrimination of Zn2+ and Cd2+ in near-aqueous media and live-cell imaging

Suvam Kumar Panda et al.

Summary: A newly designed and synthesized chemosensor capable of simultaneous detection of Zn2+ and Cd2+ is reported. The sensor shows excellent fluorescence enhancement and can distinguish between Cd2+ and Zn2+ using Cu2+ as a tool. The detection limit for Zn2+ and Cd2+ is nanomolar level. The sensor also has potential for bio-imaging applications.

Ratiometric detection and bioimaging of endogenous alkaline phosphatase by a NIR fluorescence probe

Yu-An Feng et al.

Summary: The newly designed NIR fluorescent probe SWJT-3 is capable of ratiometric determination of alkaline phosphatase (ALP) and can be used for both in vitro and in vivo detection. It is the first NIR and ratiometric fluorescent probe for imaging ALP in mice, with a large Stokes shift and low detection limit.

A NIR fluorescent probe based on C--N isomerization for fast detection of toxic acrolein

Hai Xu et al.

Summary: A highly sensitive and colorimetric NIR probe, SWJT-7, was designed and synthesized for the detection of acrolein. It showed remarkable colorimetric response, high selectivity, and fast response time. SWJT-7 was also successfully used for detecting gaseous acrolein and imaging intracellular acrolein in oxidatively stressed HepG2 cells.

A fast-response turn-on quinoline-based fluorescent probe for selective and sensitive detection of zinc (II) and its application

Jin-Tao Wang et al.

Summary: QCPCH is a Schiff base quinoline derivative that serves as a turn-on fluorescent probe for detecting Zn2+ with high selectivity, sensitivity, and rapid response time. The mechanism of sensing Zn2+ is proposed to be based on the combined effects of CHEF and PET, which is further confirmed by various analytical methods.

Fluorimetric and colorimetric detection of multianalytes Zn2+/Cd2+/F- ions via 5-bromosalicyl hydrazone appended pyrazole receptor; live cell imaging analysis in HeLa cells and zebra fish embryos

Karuppiah Krishnaveni et al.

Summary: A new tripodal, fluorogenic and chmmogenic receptor has been synthesized and successfully applied for the detection of Zn2+/Cd2+/F- ions in a DMSO/water system. The receptor showed selective turn-on response towards Zn2+/Cd2+ ions and colorimetric response towards F- ion, and could potentially be used for intracellular detection of Zn2+ ions in biological systems.

Impact of cadmium pollution on food safety and human health

Ibha Suhani et al.

Summary: Modern urbanization and industrial activities have raised concerns about heavy metal pollution, particularly cadmium which harms almost all life forms with no biological function. It enters ecosystems through natural and anthropogenic sources, impacting different trophic levels in the food chain and raising concerns for food safety and human health. The bioavailability, bioaccessibility, and accumulation of cadmium in soil-plant systems are key factors driving its transfer to different trophic levels, affecting cellular and molecular alterations.

Real-time detection and imaging of exogenous and endogenous Zn2+ in the PC12 cell model of depression with a NIR fluorescent probe

Jing Feng et al.

Summary: Depression is closely related to overactivation of NMDA receptors. A new NIR fluorescent probe, ISO-DPA, was developed for highly sensitive and rapid detection of Zn2+. The probe showed great potential in understanding the pathogenesis of depression by monitoring Zn2+ levels in solution and living cells.
