NANOTECHNOLOGY 2024; 35:335702. [PMID: 38776878 DOI: 10.1088/1361-6528/ad4ee6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/16/2024] [Accepted: 05/22/2024] [Indexed: 05/25/2024]
Abstract
One challenge of the structural design of a fluorescent probe is how to improve the detection performance on trace target analytes in complex samples. Herein a new polymer fluorescent nanoprobe (2DSP-C28) has been synthesized, by adopting a two-dimensional (2D), spiropyran (SP)-based nanosheet structure with hydrophobic long-chain alkanes (C28). Unlike a traditional SP-based small molecule probe, the 2DSP-C28probe can exhibit quantitative-fluorescent and photochromic properties. Under the detection of metal-ions, the nanoprobe in dimethyl sulfoxide aqueous solution is selectively fluorescent-quenched-responsive for Fe-ions (∼100μM), with a characteristic stoichiometric ratio of <10, a high sensitivity (limit of detection: ∼0.2μM). When the nanoprobe is incorporated into electrospun polyethylene oxide, it can be used for gas detection, and display a color-change with acid-base gas and identify the HF gas. It is expected that this new polymer fluorescent nanoprobe can be promisingly applied for rapidly environmental monitoring on the ion or gas pollution.

Anal Chim Acta 2024; 1286:341980.

Abstract
Copper ion (Cu2+) is not only a transition metal ion but also a significant environmental pollutant. The imbalance of Cu2+ content will threaten the safety of the environment and even life. The portable detection devices based on ratiometric fluorescent probes have garnered increasing attention and acclaim because of their reliable analysis parameters. Therefore, two Cu2+ ratiometric fluorescent probes (RH-1 and RH-2) were developed, which exhibit pronounced fluorescence changes, high sensitivity, excellent selectivity, and large Stokes shift. Both probes are capable of detecting Cu2+ in water and milk samples. It is worth noting that a 3D-printed fluorescence sensing device was constructed using RH-1, and a new 3D-printed copper ion detection kit was developed based on RH-2, enabling on-the-spot estimation of Cu2+ concentration. These devices significantly facilitate Cu2+ detection in daily life. RH-2 has been successfully employed for imaging Cu2+ in living cells and zebrafish. In conclusion, this work provides, for the first time, the 3D-printed ideal tools for detecting Cu2+. It also provides valuable insights for the establishment of on-site portable detection methods for other important substances.

Theoretical study on the optical properties of an ESIPT-based fluorescent probe for phosgene. J Mol Model 2022; 28:195.

Abstract
A fluorescent probe Pi with the excited-state intramolecular proton transfer (ESIPT) properties was synthesized and used to detect the phosgene in solution and gas phases. However, the detection mechanism of the fluorescent probe needs to be further studied. Herein, the density functional theory (DFT) and time-dependent density functional theory (TD-DFT) methods were adopted to explore the molecular structures and electronic spectra properties of probe and its product Pio after reacting with phosgene. Through analysis for molecular structure parameters and infrared vibrations accompanied with the hydrogen bond of Pi, it is confirmed that the intramolecular hydrogen bond of Pi is enhanced under light excitation, which illustrates the occurrence of ESIPT reaction combined with the scanned potential energy curves. It can be seen from the simulated spectra that Pi shows double fluorescence through ESIPT process, while the fluorescent product Pio exhibits the single fluorescence due to the disappearance of intramolecular hydrogen bond. Through the study on the structure and optical properties of Pi and Pio, it can be helpful to deeply understand the intrinsic mechanism of the detection of phosgene by the Pi molecule probe, which also supplies a reference to the further study about the fluorescence probe.

Abstract
Nitric oxide (NO), a ubiquitous intracellular and intercellular messenger molecule, plays vital roles in many physiological processes and is closely related to many diseases. Although a lot of fluorescent probes have been developed for real-time detection of NO successfully, the probes still suffer from poor tissue permeability and limited selectivity. In this study, a novel far-red fluorescent probe ZJL-3 based on rhodamine fluorescent dye was designed, synthesized, and used for NO determination. The probe contains a rhodamine as fluorophore and o-phenylenediamino as recognition unit. Upon addition of NO, the probe ZJL-3 showed an obvious far-red emission at 637 nm. The results of fluorescence spectrum experiments indicated that probe ZJL-3 exhibited desirable selectivity to NO. Furthermore, probe ZJL-3 has low cytotoxicity and was applied for the detection of exogenous and endogenous NO in RAW264.7 cells and C. elegans with satisfactory results.

Abstract
Sulfur mustard (SM) is recognized as one of the most lethal warfare agents. It has the potential to seriously affect public health and safety. To employ appropriate medical countermeasures and treat victims as quickly as possible, the development of a rapid and simple SM detection technique is crucial. The aim of the present study was to explore novel detection systems exhibiting excellent selectivity and high sensitivity. An SM probe, namely N-(rhodamine-B)-thiolactam-2-n-butane (SRB-NB), which was based on a thiolactam structure, was effectively designed and synthesized. The rhodamine and thiourea moieties played the roles of the chromogenic and reacting groups, respectively. Subsequently, using ionic liquids (ILs) as the solvents, a turn-on fluorescence detection system was constructed. Notably, it was found that imidazole-based ILs displayed good solubility for an SM simulant, specifically 2-chloroethyl ethyl sulfide (2-CEES). Moreover, 1-butyl-3-methylimidazolium dicyandiamide ([BMIm]DCA) IL held the maximum amount of 2-CEES (132.5 g/100 g). The SRB-NB probe exhibited better ultraviolet (UV) absorption and fluorescence properties in ILs than in other organic solvents. SRB-NB/IL was able to detect 2-CEES in liquid form with remarkable selectivity and sensitivity. The limit of detection (LOD) was established at 3.0 × 10-6 M. Importantly, SRB-NB/ILs also showed good optical response to gaseous 2-CEES and SM.

Abstract
A simple naphthalene derivative, 6-hydroxy-2-naphthohydrazide (NAH), was designed and synthesized through two facile steps reactions with the 6-hydroxy-2-naphthoic acid (NCA) as the starting material. In neat H2O (10% 0.01 M HEPES buffer, v/v, pH = 7.4), probe NAH showed a highly selective and sensitive response towards Fe3+ via perceptible color change and displayed "turn-on" dual-emission fluorescence response for Cu2+. The binding stoichiometry ratio of NAH/Cu2+ and NAH/Fe3+ were all confirmed as 1:1 by the method of fluorescence job's plot and UV-Vis job's plot, respectively. Probe NAH can be used over a wide pH range for the determination of Fe3+ (2.0-10.0) and Cu2+ (6.0-10.0) without interference from other co-existing metal ions. A possible detection mechanism was the hydrolysis of NAH upon the addition of Fe3+ or Cu2+, thereby leading to the formation of 6-hydroxy-naphthalene-2-carboxylic acid (NCA) which was further confirmed by the various spectroscopic techniques including FT-IR, 1H NMR titration and HRMS. Moreover, NAH was successfully applied to the detection of Cu2+ and Fe3+ in tap water, ultrapure water and BSA.
