“…These two forms exhibit a dramatic difference in physiological activity. The present detections mainly focus on Fe 3+ and Fe ions [41][42][43], so the development of a fast and accurate detection method to Fe 2+ is of crucial importance.…”

This paper reports the preparation of green-emissioned CDs by a one-step hydrothermal route with DL-malic acid and ethylenediamine as raw materials and further explored the impacts of the amount of reactants, the reaction time, and temperature upon the optical properties of prepared CDs, to select the optimal preparation parameters. The optical properties, surface groups, and element components of the prepared CDs have been systematically studied by UV-Vis absorption spectra, fluorescence spectra, FTIR, EDS, and XPS. The prepared CDs have been applied to realize the fingerprint development, fluorescence ink, and, specifically, the detection of Fe2+ through an inner filter effect with its detection range at 2.0×10−7−2.3×10−5 mol/L.

“…The basic mechanism of the fluorescent method is that the fluorescence parameters (such as fluorescence intensity, lifetime, and spectrum) change in response to the concentration variations of some ions. Until now, numerous fluorescent sensors based on chelation-enhanced fluorescence [98,99] photo-induced electron transfer [92], aggregation-induced emission effect [100], and intramolecular charge transfer [101] have already been reported for heavy metal monitoring. Leray's group developed several optofluidic devices that incorporated fluorimetric detection for the monitoring of heavy metals such as aluminum and cadmium [92,93,102].…”

Determining the distributions and variations of chemical elements in oceans has significant meanings for understanding the biogeochemical cycles, evaluating seawater pollution, and forecasting the occurrence of marine disasters. The primary chemical parameters of ocean monitoring include nutrients, pH, dissolved oxygen (DO), and heavy metals. At present, ocean monitoring mainly relies on laboratory analysis, which is hindered in applications due to its large size, high power consumption, and low representative and time-sensitive detection results. By integrating photonics and microfluidics into one chip, optofluidics brings new opportunities to develop portable microsystems for ocean monitoring. Optofluidic platforms have advantages in respect of size, cost, timeliness, and parallel processing of samples compared with traditional instruments. This review describes the applications of optofluidic platforms on autonomous and in situ ocean environmental monitoring, with an emphasis on their principles, sensing properties, advantages, and disadvantages. Predictably, autonomous and in situ systems based on optofluidic platforms will have important applications in ocean environmental monitoring.

“…38,39 Julolidine moiety often exhibited a good colorimetric response with target analytes because it has excellent chromogenic properties. 40,41 These facts led us to expect that the existence of both the benzophenone and the julolidine moieties in a chemosensor may show unique chromogenic properties to specific analytes. Therefore, we developed the sensor ANBP through a combination of the two groups to develop a new unique chemosensor.…”

A novel selective colorimetric chemosensor ANBP ((E)-(2-(((8-hydroxy-2,3,6,7-tetrahydro-1H,5Hpyrido[3,2,1-ij]quinolin-9-yl)methylene)amino)-5-nitrophenyl)(phenyl)methanone), based on the combination of benzophenone group and julolidine chromophore, was synthesized. Sensor ANBP showed rapid colorimetric responses toward Cu 2+ (pale orange to pink) and F − (orange to blue). The detection limit by ANBP to Cu 2+ (6.82 µM) was far below WHO guideline value (31.3 µM). Moreover, ANBP could quantify Cu 2+ in aqueous samples. 1:1 binding mode between ANBP and Cu 2+ or F − was proposed by ESI-mass analyses and Job plots. The remarkable color changes with Cu 2+ and F − resulted from the intramolecular charge transfer (ICT) effect, which was demonstrated by theoretical calculations.
