“…These changes in electron density may alter the biological activity of ligands by affecting intermolecular interactions and lipophilicity. [ 15–17 ] By contrast, the imidazolium‐containing ionic liquid (IL) ligands which essentially consist of an aromatic heterocycle containing two nitrogen atoms, with one in the cationic form, are perhaps the most widely studied in the biological field because of their unique physical and chemical properties. [ 18–20 ] Moreover, extensive biochemical and pharmacological studies have confirmed imidazole as effective compounds in treating various strains of microorganisms.…”

Four metal complexes, IL‐OPPh2‐Ru‐p‐cymene (3), IL‐OPPh2‐Ru‐benzene (4), IL‐OPPh2‐Ir‐Cp* (5), IL‐OPPh2‐Rh‐COD (6), have been evaluated for in vitro antioxidant activity such as 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) radical scavenging and reducing power activity. Maximum scavenging activity (71.43%) was obtained with IL‐OPPh2‐Ru‐p‐cymene, whereas IL‐OPPh2‐Rh‐COD showed the highest reducing power ability. The complexes were also studied for their antimicrobial activity against three Gram‐positive and three Gram‐negative bacteria. In addition, DNA binding of the complexes was evaluated using calf thymus DNA. Both Ru(II) complexes exhibited good DNA‐binding activity while the other complexes did not have any activity. Furthermore, ab initio quantum calculations of four complexes were also carried out using density functional theory to better understand their chemical behaviors.

“…Hexaconazole is classied under the triazole group, widely used on cereal and ornamental plants to control fungi, particularly Ascomycetes and Basidiomycetes. [10][11][12] It has systemic demethylation inhibitors (DMI) that act mainly on the vegetative stage of fungi by blocking the mycelial growth either inside or on the surface of the host plant. 13 In addition, dazomet is a soil fumigant that releases methyl isothiocyanate (MITC) when it comes into contact with water.…”

“…Simultaneously, the newly formed oxygen-containing functional groups, such as the quinone groups, are attacked by the hydroxyl radicals. [28][29][30] In this fashion, the Fenton reaction induced by the presence of zero-valent iron and H 2 O 2 (30%) can restart. An excessive presence of zero-valent iron reduces the -COOH on the surface of the GOQDs into -OH under acidic conditions.…”

In recent years, graphene oxide quantum dots (GOQDs) have emerged as novel nanomaterials for optical sensing, bioimaging, clinical testing, and environmental testing. However, GOQDs demonstrate unique photoluminescence properties, with GOQDs having quantum limitations and edge effects that often affect the accuracy of the test results in the sensory field. Herein, GOQDs with a large content of hydroxyl groups and low fluorescence intensity were first prepared via an improved Fenton reaction in this study, which introduces a large amount of epoxy groups to break the C-C bonds. The synthesized GOQDs show no significant variation in the fluorescence intensity upon ultraviolet and visible light excitations. We further utilized the GOQDs as fluorescence quenchers for different fluorescent dyes in real-time fluorescence quantitative polymerase chain reaction (qRT-PCR), and verified that the addition of GOQDs (5.3 mg ml À1 ) into a qRT-PCR system could reduce the background fluorescence intensity of the reaction by fluorescence resonance energy transfer (FRET) during its initial stage and its non-specific amplification, and improve its specificity. In addition, the qRT-PCR method could detect two different lengths of DNA sequences with a high specificity in the 10 4 to 10 10 copies per ml range. It is of paramount importance to carry out further investigations to establish an efficient, sensitive, and specific RT-PCR method based on the use of GOQD nanomaterials as fluorescence quenchers.
