The fouling and passivation of the electrodes tend to reduce the sensitivity and lifetime of the electrodes. In this work, the mesoporous carbon-doped La-TiO 2 modified electrode not only has a good detection signal for catechol and hydroquinone, but also can achieve the purpose of electrode regeneration under illumination. A series of porous carbon materials LTOF-T (La-Ti Organic Frameworks-Temperature, LTOF-T) were prepared by hydrothermal method and pyrolysis method using La(NO 3 ) 3 ⋅6H 2 O, p -tricarboxylic acid, citric acid monohydrate, and tetra- n -butyl titanate as raw materials. The materials were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), N 2 adsorption–desorption, and Raman spectroscopy. The electrochemical behaviors of catechol (CA) and hydroquinone (HQ) on different electrodes were investigated by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). Under the optimal conditions, HQ and CA concentrations were linear in the range of 0.4–20 μmol/L, and the detection limits were 0.039 μmol/L (HQ) and 0.034 μmol/L (CA) at the signal noise ratio of 3. The electrode can be regenerated under visible light irradiation within 60 min.

An electrochemical sensor is described for the simultaneous determination of the pollutants catechol (CC) and hydroquinone (HQ). A glassy carbon electrode (GCE) was modified with reduced graphene oxide, Fe 3 O 4 and gold nanoparticles and then showed a pair of well-defined voltammetric peaks for CC and HQ. Its oxidation peak potentials (located at 0.21 and 0.10 V vs. Ag/AgCl) are well separated, and this makes it suitable for simultaneous determination of the two isomers. Under optimal conditions, the oxidation peak currents of CC and HQ increase linearly in the 0.05–550 μM and 0.1–500 μM concentration ranges, even in the presence of 0.1 mM of the respective other isomer. The detection limits are 0.02 and 0.17 μM (at S/ N = 3), respectively. The modified GCE exhibits good selectivity and recovery when applied for the analysis of spiked wastewater.
Ternary hybrid nanomaterials of rGO-Fe 3 O 4 -Au was developed for simultaneous electrochemical determination of catechol (CC) and hydroquinone (HQ).

Objective Hydroquinone (HQ) is globally regarded as the gold-standard topical agent for melasma treatment. However, its clinical utility is limited by several challenges: susceptibility to oxidation induced by light, air, and metal ions, which generates harmful byproducts and triggers adverse effects (e.g., skin irritation, pruritus, and dermatitis). Moreover, excessively high concentration in the skin of hydroquinone due to the burst release of HQ may cause melanocyte cytotoxicity, while systemic penetration raises additional safety concerns. To overcome these limitations and enhance the therapeutic applicability of HQ, this study aims to develop strategies that mitigate its instability and optimize its delivery profile. Methods In this study, an oil-in-water cream containing hydroquinone cyclodextrin inclusion complex (HQ-HPCD) was designed with PO as the oil phase matrix to improve the treatment of melasma. Results As expected, the in vitro release profile of HQ-HPCD cream exhibited near-zero-order kinetics, effectively mitigating the irritation associated with burst release-induced peak concentrations. The HQ-HPCD inclusion complex demonstrated enhanced photostability and oxidative resistance compared to free HQ. Then it was confirmed by B16F10 cells that the HQ-HPCD increased the IC 50 of HQ by 4.6 times. Moreover, skin condition, tyrosinase activity, SOD (Superoxide Dismutase), MDA (Malondialdehyde) and melanin content in the mice were detected and the results were in line with the in vitro assays, which showed that PO-HQ-HPCD cream has higher resistance to melanin deposition and lower irritation. Conclusions This study successfully developed a topical formulation that enhances the stability of hydroquinone (HQ) while achieving its sustained release in the epidermal layer, thereby improving its clinical applicability of melasma.

Abstract Rod-shaped MnO 2 was synthesized by hydrothermal method. Ag@MnO 2 NRs were prepared with the Ag nanoparticles grown on the surface of rod-shaped MnO 2 by different reducing agents. The Ag@MnO 2 NRs were characterized by X-ray diffractometry, scanning and transmission electron microscopy, as well as X-ray photoelectron spectroscopy. The catalytic performance, catalytic mechanism and kinetic equation of the Ag@MnO 2 NRs were investigated. The as-prepared Ag@MnO 2 NRs were endowed with oxidase-like activity to catalyze the oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB) to a blue product without H 2 O 2 . Due to the inhibition of hydroquinone (HQ) on TMB oxidation, a simple, rapid, sensitive, and selective colorimetric sensor was set for the detection of HQ concentration in actual water. This method was established with an excellent linear range from 5–30 μM and a low detection limit of 1.7 μM. The colorimetric means could be availably used for the detection of HQ in river water samples and the RSD < 4.97%. The above results illustrated that the Ag@MnO 2 NRs had a great application prospect in environmental detection.

In this paper, a novel biosensor based on Carbon dots (C-dots) for sensitive detection of hydroquinone (H 2 Q) is reported. It is interesting to find that the fluorescence of the C-dots could be quenched by H 2 Q directly. The possible quenching mechanism is proposed, which shows that the quenching effect may be caused by the electron transfer from C-dots to oxidized H 2 Q-quinone. Based on the above principle, a novel C-dots based fluorescent probe has been successfully applied to detect H 2 Q. Under the optimal condition, detection limit down to 0.1 μM is obtained, which is far below U.S. Environmental Protection Agency estimated wastewater discharge limit of 0.5 mg/L. Moreover, the proposed method shows high selectivity for H 2 Q over a number of potential interfering species. Finally, several water samples spiked with H 2 Q are analyzed utilizing the sensing method with satisfactory recovery. The proposed method is simple with high sensitivity and excellent selectivity, which provides a new approach for the detection of various analytes that can be transformed into quinone .

In this work, a conductive hydrogel was successfully synthesized, taking advantage of the high number density of active amino and hydroxyl groups in carboxymethyl chitosan and sodium carboxymethyl cellulose. These biopolymers were effectively coupled via hydrogen bonding with the nitrogen atoms of the heterocyclic rings of conductive polypyrrole. The inclusion of another biobased polymer, sodium lignosulfonate (LS), was effective to achieve highly efficient adsorption and in-situ reduction of silver ions, leading to silver nanoparticles that were embedded in the hydrogel network and used to further improve the electro-catalytic efficiency of the system. Doping of the system in the pre-gelled state led to hydrogels that could be easily attached to the electrodes. The as-prepared silver nanoparticle-embedded conductive hydrogel electrode exhibited excellent electro-catalytic activity towards hydroquinone (HQ) present in a buffer solution. At the optimum conditions, the oxidation current density peak of HQ was linear over the 0.1–100 μM concentration range, with a detection limit as low as 0.12 μM (signal-to-noise of 3). The relative standard deviation of the anodic peak current intensity was 1.37% for eight different electrodes. After one week of storage in a 0.1 M Tris-HCl buffer solution at 4 °C, the anodic peak current intensity was 93.4% of the initial current intensity. In addition, this sensor showed no interference activity, while the addition of 30 μM CC, RS, or 1 mM of different inorganic ions does not have a significant impact on the test results, enabling HQ quantification in actual water samples.Keywords:hydroquinone;silver nanoparticle-embedded;conductive hydrogel;electrochemical sensor

This study converted sewage sludge into a carbonaceous catalyst via pyrolysis and employed it in the ozonation of hydroquinone. The catalyst was characterized by Mössbauer spectroscopy, X-ray photoelectron spectroscopy, temperature programmed desorption, scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy and X-ray diffraction. Intermediate products were detected by gas chromatography–mass spectrometry, and a pathway for hydroquinone degradation was proposed. The results showed that sludge pyrolyzed at 700 °C promoted hydroquinone degradation, compared with commercial activated carbon derived from coal. When the catalyst dose was 0.5 g/L, the hydroquinone (200 mg/L) removal rate reached 97.86% after exposure to ozone (the ozone concentration was 17 mg/L and the flow rate was 50 mL/min) for 60 min. The results indicated that basic groups contributed to the catalysis.

The detection of organic pollutants in water was deemed critical for safeguarding aquatic ecosystems, maintaining human health, and upholding water quality standards. In this study, a novel electrochemiluminescence (ECL) sensor was proposed for the sensitive detection of hydroquinone (HQ) in lake water, utilizing a glassy carbon electrode (GCE) modified with silver/luminol-functionalized carbon microspheres (GCE/CM@Ag/Lu). Due to the consumption of H 2 O 2 by HQ, the ECL signal was attenuated, enabling the quantitative detection of HQ. Under optimized conditions, the linear range for HQ ranged from 1.0 × 10 −4 –1.0 × 10 −10 mol L −1 , with a limit of detection (LOD) of 3.3 × 10 −11 mol L −1 (S/N = 3). The proposed ECL sensor shows promising potential to open new avenues for water quality assessment.

In this study, stable CotA laccase from Bacillus subtilis 168 was adsorbed on electrode modified with a thiol graphene-gold nanoparticle (thGP-AuNPs) nanocomposite film. The novel bacterial laccase biosensor was employed for quantitative detection of hydroquinone (HQ) and the electrochemical properties of this laccase biosensor were investigated. The results indicate that the immobilized CotA shows great oxidation activity towards HQ in the presence of oxygen and the biosensor shows linear electrocatalytic activity in the concentration range from 1.6 to 409.6 μM, with a detection limit of 0.3 μM. Further, the CotA modified electrode, when compared to fungal laccase-modified biosensors, shows better alkaline stability (retaining approximately 80 % and 70 % of response current at pH 8 and 9, respectively) and reusability (retaining ∼87 % of response current after 100 days). The development of this new kind of laccase on a biosensor will offer a novel tool for substance detection applications in hostile environments, especially for industrial pollutants.

This work describes a simple and sensitive fluorescent method for detection of hydroquinone utilizing conjugated polymer nanoparticles (CPNs). The CPNs serve both as a catalyst to accelerate the conversion of hydroquinone to benzoquinone and a fluorescent probe . In the presence of hydroquinone, the fluorescence of CPNs can be effectively quenched by benzoquinone. The detection limit of hydroquinone was down to 5 nM and excellent selectivity toward possible interferences was obtained. This method was successfully applied for hydroquinone detection in lake water and satisfactory results were achieved.

A facile strategy to modify the surface of K 2 SiF 6 :Mn 4+ (KSFM) with commercially available hydrophilic hydroquinone (HQ) has been developed and waterproof stability (moisture resistance) of the KSFM has been significantly improved. It has been demonstrated that there are strong interactions between KSFM and HQ on the interface due to the hydrogen bonds of fluorine in KSFM with hydrogen in HQ. The relative luminous intensity of HQ-modified KSFM (denoted as KSFM-HQ) remained 99.7% of its initial value after immersion in water for 336 h, remarkable higher than that of KSFM which remained only 38.0%. It is proposed that the high water resistance of KSFM-HQ is achieved via two possible mechanisms: in situ decomposition of dark brown manganese (owing to the hydrolysis of [MnF 6 ] 2− ) on the KSFM crystal surface and consequently the formation of a more protective Mn 4+ -free layer. The process effectively combines the advantages of transparent organic materials (herein HQ) before immersion in water and durable moisture resistance of inorganic materials (herein K 2 SiF 6 ) on surface after immersion in water. The importance of HQ loading on moisture-sensitive fluoride phosphors has been further confirmed by using HQ-treated K 2 GeF 6 :Mn 4+ (KGFM) as an additional example. This strategy provides a one-of-a-kind way to the development of water-resistant Mn 4+ -doped fluoride phosphors with high luminous stability for potential applications in water-borne fluorescent anti-counterfeiting ink and even warm WLEDs operating in high humidity.

Hydroquinone poses a major threat to human health and is refractory to degradation, so it is important to establish a convenient detection method. In this paper, we present a novel colorimetric method for the detection of hydroquinone based on a peroxidase-like Pd nanozyme. The vancomycin-stabilized palladium nanoparticles (Van-PdnNPs, n = 0.5, 1, 2) were prepared using vancomycin as a biological template. The successful synthesis of Van-PdnNPs (n = 0.5, 1, 2) was demonstrated by UV-vis spectrophotometry, transmission electron microscopy, and X-ray diffraction. The sizes of Pd nanoparticles inside Van-Pd0.5NPs, Van-Pd1NPs, and Van-Pd2NPs were 2.6 ± 0.5 nm, 2.9 ± 0.6 nm, and 4.3 ± 0.5 nm, respectively. Furthermore, Van-Pd2NPs exhibited excellent biocompatibility based on the MTT assay. More importantly, Van-Pd2NPs had good peroxidase-like activity. A reliable hydroquinone detection method was established based on the peroxidase-like activity of Van-Pd2NPs, and the detection limit was as low as 0.323 μM. Therefore, vancomycin improved the peroxidase-like activity and biocompatibility of Van-Pd2NPs. Van-Pd2NPs have good application prospects in the colorimetric detection of hydroquinone.Keywords:nanozyme;vancomycin;palladium;nanoparticles;detection
