Emergent application of antimicrobial strategies as symptomatic treatment in coronavirus disease (COVID-19) and linkage of severe acute respiratory syndrome coronavirus2 with microbial infections, has created colossal demand for antimicrobials. For the first time, this communication explore the physicochem., antifungal, antibacterial, and photocatalytic properties of biogenic magnesium nanoparticles (MgNPs), synthesized using essential oil of Cymbopogon flexuosus’s as an efficient multifunctional reducing and stabilizing/capping reagent. It is observed that MgNPs (ranging in size: 8-16 nm) of varying phytochem. compositions (MgS1, MgS2, MgS3) exhibited various useful physicochem., antimicrobial, and photocatalytic properties. FTIR outcomes highlight the functional biomols.-assisted reduction of Mg from Mg⁺ to Mg⁰. Among all, MgS3-Nps owing to the smallest particle size exhibited superior photocatalytic efficacy (91.2%) for the methylene blue degradation upon direct exposure to the sunlight for 3 h without using any reducing agents. Fabricated MgNPs also exhibited excellent antifungal (against Fusarium oxysporum) and antibacterial (vs. Staphylococcus aureus and Escherichia coli) efficacies compared to state-of-the-art antimicrobial agents deployed for the treatment of infectious diseases. Based on this investigated greener approach, imperative from economic and environmental viewpoint, such essential oil based-MgNPs can be a potential nanosystem for various industrial applications where photocatalytic, and biomedical attributes are the key requirements.

And the article was included in Journal of Photochemistry and Photobiology, A: Chemistry in 2022.SDS of cas: 61-73-4 This article mentions the following:

An environmentally benign method for preventing the photofading of organic dyes was developed using chlorogenic acids, also known as caffeoylquinic acids (CQAs), which can be obtained in large quantities from agricultural wastes. In this study, 5-caffeoylquinic acid (5-CQA) and 4,5-dicaffeolyquinic acid (4,5-diCQA) were used as singlet oxygen (¹O₂) quenchers, and their suppression mechanisms were evaluated by the self-catalyzed photobleaching reactions of methylene blue (MB) and rose bengal (RB) in aqueous solutions at different pH values. Light irradiation experiments, half-wave oxidation potentials measurements, LC-MS, and NMR demonstrated that CQAs effectively inhibited the photofading of the dyes in the pH range of 4-9 with two independent reaction mechanisms. 4,5-diCQA was more effective in preventing the photofading than 5-CQA. The kinetic anal. estimated the ¹O₂ quenching constants of CQAs (kq = 7.22 x 10⁷ M^-1 s^-1 and 9.33 x 10⁷ M^-1 s^-1 for 5-CQA and 4,5-diCQA) and the bimol. rate constant for the chem. quenching of ¹O₂ by MB (kf = 2.88 x 10⁴ M^-1 s^-1). Comparing these rate constants revealed that the quenching reactions of ¹O₂ by CQAs were more predominantly than the photofading reaction of MB.

Occurrence and partitioning of bisphenol analogues, triclocarban, and triclosan in seawater and sediment from East China Sea was written by Xie, Jiahui;Zhao, Nan;Zhang, Yingying;Hu, Hongmei;Zhao, Meirong;Jin, Hangbiao. And the article was included in Chemosphere in 2022.Formula: C13H9Cl3N2O This article mentions the following:

Bisphenol analogs (BPs), triclocarban (TCC), and triclosan (TCS) are well-known environmental endocrine disrupters. Many studies have characterized their occurrence in the freshwater environment. However, their environmental behaviors in the coastal marine environment remain poorly understood. Here, matched seawater and sediment samples were collected from East China Sea, and analyzed for 13 BPs (including halogenated derivatives of bisphenol A), TCC, and TCS. Bisphenol A (BPA; mean 23 ng/L) was the predominant BP in seawaters, followed by tetrabromobisphenol A (TBBPA; 2.3 ng/L) and bisphenol S (BPS; 2.2 ng/L). Seawater concentrations of TCS (<LOD-8.7 ng/L) were much higher (p < 0.01) than that of TCC (<LOD-0.33 ng/L). In sediments BPA was still the major BP (mean 13 ng/g dw, dry weight), followed by bisphenol F (1.6 ng/g dw) and BPS (0.69 ng/g dw). All sediment samples contained measurable TCC (0.12-6.6 ng/g dw), while TCS was occasionally detected. For the first time, this study reports the environmental occurrence of bisphenol M and 4,4′-sulfonylbis (2-aminophenol) (a first discovered BPS analog) in seawaters and sediments. Spatially, inshore seawater and sediment samples contained higher (p < 0.01) BPA and BPS concentrations, compared with offshore samples. The mean log-transformed sediment-seawater partitioning coefficients (log K_oc) ranged from 2.3 (TBBPA) to 4.0 (TCC). The log Koc values of BPA, BPS, and BPAF were lower than those previously reported in the freshwater environment. Overall, this study provides first data on the spatial distribution patterns and partitioning behaviors of BPs, TCC, and TCS in marine environment. In the experiment, the researchers used many compounds, for example, 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2Formula: C13H9Cl3N2O).

And the article was included in Sustainable Environment Research in 2022.Product Details of 61-73-4 This article mentions the following:

In this present study, a novel method to fabricate bimetallic Fe-Co catalyst supported on waste silica was investigated for the photo-Fenton-like (PFL) degradation of Methylene Blue (MB) dye. The uniqueness of this work is on the preparation of the catalyst via fluidized-bed crystallization (FBC) process. Under the optimum conditions of initial pH of 3.0, 3.0 mM of H2O2, and 1.0 g L-1 of FBC-derived Fe-Co/SiO2 catalyst (fFCS), the maximum response for the decoloration and mineralization efficiencies of 20 mg L-1 of MB in 60 min were 100 and 65%, resp. Compared to the impregnated Fe-Co/SiO2 catalyst, the fFCS catalyst exhibited comparable decoloration and mineralization efficiencies, and relatively lower metal leaching for both iron and cobalt. Superoxide radical was unveiled to be the dominant reactive oxygen species in the PFL system over the fFCS catalyst. The catalysts were characterized by Fourier Transform IR spectroscopy, Energy Dispersive X-ray spectroscopy and SEM. The results show the successful incorporation of iron and cobalt on the surface of the SiO2 support material.

Construction of a ratiometric electrochemical aptasensor based on graphdiyne-methylene blue and Fc-labeled hairpin for cyclic signal amplification detection of kanamycin was written by Gao, Xiaolin;Sun, Zhicong;Wang, Xiaoyang;Zhang, Wanqi;Wang, Yue;Han, Jie;Sun, Xia;Guo, Yemin;Li, Falan;Xu, Shicai. And the article was included in Sensors and Actuators, B: Chemical in 2022.Reference of 61-73-4 This article mentions the following:

Based on ferrocene (Fc)-labeled primers and graphdiyne-methylene blue (GDY-MB) nanocomposite, a ratiometric electrochem. aptasensor was prepared for high-precision detection of kanamycin (KAN). The Fc-labeled primer hybridized with the aptamer forms a rigid structure. When KAN was specifically bound to an aptamer, a primer with a self-complementary sequence was released to form a hairpin structure (HP), drawing the Fc close to the electrode surface, resulting in enhanced IFc. Exonuclease I (Exo I) was used to cleave the single-stranded aptamer and release the target, effectively increasing the cyclic amplification signal. The phosphorylation was carried out at the 3 end of the primers to prevent HP cleavage. The chitosan – antimony tin oxide (CS-ATO) and AuNPs were used to further modified the electrodes to double the signal amplification. Under the optimal exptl. conditions, the KAN concentration exhibited a strong linear relationship with IFc/IMB. The R2 (0.997) of the calibration curve was greater than the R2 (0.960) of the standard curve of KAN concentration and IFc, which indicates the robustness of the ratiometric electrochem. sensor. The limit of detection (LOD) was 6.044 nM. The aptasensor exhibits strong stability and specificity for successfully detection of KAN in real milk samples. In the experiment, the researchers used many compounds, for example, 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4Reference of 61-73-4).
