Rapid, ultrasensitive, highly selective detection of toxic Hg(II) ions in seabass, swordfish and water samples

AIEE Active Azomethine-Based Rhodamine Derivative For Ultrasensitive Multichannel Detection of Au3+ Through a Fluorimetrically, Electrochemically, and RGB-Based Sensing Assay

“…However, these techniques are most complicated, expensive, time-taking, and labor-intensive. Contrary to traditional methods, colorimetric, fluorescent, and electrochemical approaches have numerous advantages, including simplicity, ultrasensitivity, selectivity, inexpensive, rapid, nondestructive nature, real-time monitoring of biological samples, and repeatability. − …”

Monitoring of Hypochlorite Level in Fruits, Vegetables, and Dairy Products: A BODIPY-Based Fluorescent Probe for the Rapid and Highly Selective Detection of Hypochlorite

“…BOD–Br was synthesized according to the literature procedure with slight modifications . To a mixture of BOD–Br (100 mg, 0.248 mmol), 5-formyl-2-thienylboronic acid (50.3 mg, 0.322 mmol), and K 2 CO 3 (5.00 mL, 2 M) in a Schlenk tube and under nitrogen was added THF (20 mL).…”

“…Hypochlorite (ClO – ), which is a strong oxidizing agent, is widely used in food, vegetable, and dairy products to destroy microbial activity, delay food spoilage, and extend the shelf-life. , Additionally, because of its critical antimicrobial properties, ClO – is also used as a disinfectant for drinking water, wastewater, industrial waste treatment, and swimming pool treatment. − On the other hand, the acceptable chlorine level ranges from 50 to 200 mg/L for fruits and vegetables, excess amount of which could damage organs and tissues resulting in several diseases such as cardiovascular, neuron degeneration, kidney, arthritis, and cancer. − Therefore, development of a rapid and efficient method for the selective and sensitive determination of ClO – is in high demand. Compared to traditional methods, fluorescent probes have many advantages, such as sensitivity, selectivity, fast response, and real-time monitoring, thus garnering tremendous attention from researchers. − Although some fluorescent probes have been developed to detect ClO – , they have drawbacks, such as slow response, high detection limits, low quantum yields, turn-off response, cumbersome synthesis, and, especially, inability to be applied in actual food samples, which prompted us to develop a fluorescent probe with superior properties of selective and sensitive detection of ClO – to overcome such drawbacks. − …”

A mitochondrion-targeted fluorescent probe based on ESIPT phthalimide for the detection of Hg2+ with large Stokes shift

“…1 Mercury can be found in the elemental or ionic form, but mostly in the form of Hg 2+ existing in the environment. 2 Due to its release from natural sources and human activity, 3 mercury pollution is found extensively in air, water, soil, plants, and animals, 4 which can enter into the human body via different ways. Because of its high biological accumulation and strong affinity for sulfur-containing proteins and enzymes, it not only causes damage to the kidney and liver, 5 but also induces serious diseases, including motor disorders, cognitive impairment, nerve and immune dysfunction, Minamata disease, cancer, and even death.…”
