“…Sensor 41 chelates Cd 2+ /Zn 2+ , which inhibits the C N isomerization, increases (51.1/17.7 fold) the fluorescence, and changes from dark to light-blue/green fluorescence. 18 In addition, the emission peak at 451 nm red shifts to 480 nm/500 nm, and the fluorescence intensity at 480 nm/500 nm is linearly related to the concentration of Cd 2+ /Zn 2+ . The complexing constants of open-ring isomer for Cd 2+ is 5.95 × 10 4 L mol −1 and for Zn 2+ is 4.9 × 10 4 L mol −1 , and the detection limits for Cd 2+ is 8.69 × 10 −9 mol L −1 and for Zn 2+ is 3.67 × 10 −8 mol L −1 .…”

“…14 ), the conversion between their open-ring and closed-ring isomers can be realized by irradiation at 297 nm and >500 nm. 18,28 The properties of the two probes were studied in methanol solution and 350 nm light excitation. Because EDTA can make these probes bind to Cd 2+ reversibly, the author used Cd 2+ /EDTA and UV/vis as the input stimulus and the fluorescence intensity (sensors 40 and 41 were recorded at 476 nm and 480 nm, respectively) of probes in the presence of Cd 2+ as the output to construct the logic circuit.…”

“… 19–23 Nevertheless, most of these detection methods require expensive equipment, tedious procedures and skilled operators, and have the characteristics of low detection sensitivity, high economic costs and time-consuming. 18,23–25 By contrast, fluorescent probe detection has the characteristics of strong specificity, high sensitivity, low detection limit, high accuracy, low cost, and visualization, which can replace traditional analysis methods to detect Cd 2+ . 15,16,26–28 Therefore, the research and application of Cd 2+ fluorescent sensors is of great interest to many scientific fields, ranging from supramolecular chemistry to life sciences.…”

“…Traditional methods for detecting Cd 2+ using fluorescence include a Cyclen-based Fluorescent Chemosensor [ 46 ] and a radiometric fluorescent peptide sensor [ 47 ]. However, these techniques have drawbacks such as complicated operation, low monitoring sensitivity, and consuming time [ 48 , 49 , 50 ]. In contrast, fluorescent biosensors based on aptamers offer high sensitivity, precision, and a low detection limit.…”

Cd2+, a major environmental pollutant, is heavily toxic to human health. Many traditional techniques are high-cost and complicated; thus, developing a simple, sensitive, convenient, and cheap monitoring approach is necessary. The aptamer can be obtained from a novel method called SELEX, which is widely used as a DNA biosensor for its easy acquisition and high affinity of the target, especially for heavy metal ions detection, such as Cd2+. In recent years, highly stable Cd2+ aptamer oligonucleotides (CAOs) were observed, and electrochemical, fluorescent, and colorimetric biosensors based on aptamers have been designed to monitor Cd2+. In addition, the monitoring sensitivity of aptamer-based biosensors is improved with signal amplification mechanisms such as hybridization chain reactions and enzyme-free methods. This paper reviews approaches to building biosensors for inspecting Cd2+ by electrochemical, fluorescent, and colorimetric methods. Finally, many practical applications of sensors and their implications for humans and the environment are discussed.

Lithium‐ion batteries are the most commercially successful electrochemical devices, extensively used in intelligent electronics, electric vehicles, grid energy storages, etc. However, there still needs to be further improvement of their performance such as in energy density, cyclability, rate capability, and safety. To do so, it is necessary to understand the detailed structural evolution progress inside the battery. Many advanced imaging techniques have been developed to directly monitor the status and get some key information inside the battery. For advanced imaging techniques, superhigh resolution, fully informative function, nondestruction of the sample, and in situ observation are required. This review introduces and discusses some recent important progress on a variety of advanced imaging techniques for battery research. These imaging techniques have enabled the visualization of sub‐micrometer level chemical valence distribution, evolution of solid‐electrolyte interface, Li dendrite growth, and trace amount of gassing, etc., which greatly promote the development of rechargeable batteries. Of particular note, a new ultrasonic imaging technique has been recently developed to monitor gas generation, the electrolyte wetting process, and the state of charge in the battery. Finally, a perspective is given on some future developments in the imaging techniques for Li‐ion batteries and other rechargeable batteries.
