In this study, zinc nanoparticles (Zn NPs) were synthesized from the leaves of the plant Hypericum calycinum L by the biogenic method. Ultra-violet visible spectrum (UV-Vis), Fourier transmission electron spectroscopy (FTIR), transmission electron microscopy (TEM), and X-Ray were used to examine the absorbance, vibration bands, morphological structure, particle size, and crystalline size of the synthesized Zn NPs, respectively. Diffraction characterization (XRD) was performed. According to the results obtained, it was calculated that NPs gave peaks in the absorbance ranges of 274 and 370 nm, had a size of 29.066 ± 10.561 nm, and their crystalline size was 16 nm. Then, photocatalytic processes were started for the removal of methylene blue (MB) dye by combining the catalysis of NPs under the photocatalysis of sunlight. The degradation process provided by photocatalytic processes was carried out every half hour for 150 minutes. As a result of 150 minutes, the photodegradation efficiency was calculated to be 70%. This study supports future photodegradation studies for the removal of waste dyestuffs.

“…Traditionally, Cat has been quantified by using gas chromatography, high‐performance liquid chromatography, fluorescence spectrometry, capillary electrophoresis, as well as electrochemical sensors (el‐Hady & el‐Maali, 2008; Manasa et al, 2017; Yang et al, 2000). Electrochemical sensors are popular because of their ease of use, sensitivity, quick reaction, and low cost (Alizadeh et al, 2022; Sun et al, 2022; Wang et al, 2022). To date, a large number of studies on Cat electrochemical sensors have been reported (Della Pelle et al, 2019; Ezhil Vilian et al, 2015; Gomes et al, 2022; Şenocak et al, 2019).…”

Catechin (Cat) is one of the primary functional components of tea, and its accurate detection is significant for understanding the health benefits of tea. In this study, cyclodextrin nanosponges (CDNS) were prepared and employed to combine with graphene quantum dots (GQDs) and carboxylated multi‐walled carbon nanotubes (MWCNTs‐COOH) to form a CDNS/GQDs/MWCNTs‐COOH composite. Scanning electron microscope and X‐ray diffraction were used to characterize the composite which was used to build a new electrochemical Cat sensor. The abundance of cavities, intermolecular gaps, and surface active groups of CD molecules endowed CDNS with remarkable Cat enrichment capacity. Due to the outstanding biocompatibility of GQDs, the good electrocatalytic activity of MWCNTs‐COOH, and the enrichment capacity of CDNS, the composite modified glass carbon electrode (GCE) exhibited excellent electrochemical sensing performance. The CDNS/GQDs/MWCNTs‐COOH/GCE showed a sensitive peak current response to catechins in the linear range between 2 × 10−8 and 1.2 × 10−6 M, with a minimum limit of detection (S/N = 3) of 4.45 nM. The sensor has also been successfully applied for catechin detection in tea beverages.

“…Notwithstanding their efficacy, these strategies are beset by time consumption and the need for costly instrumentation, skilled technicians, and pretreatment processes. By contrast, electrochemical methods are regarded as potential means for the detection of RAC 2,13 and even other biomolecules [14][15][16][17][18] due to their convenient operation, rapid response, and simple sample 3D-rGO/Pd/b-CD; the optimization of recognition conditions; approach for determining the limit of detection (LOD); Job's plot determination; comparison of differently modied electrodes for the determination of RAC; determination of RAC in pork samples with 3D-rGO/Pd/b-CD/GCE; 1 pretreatment procedure. Very recently, numerous twodimensional (2D) graphene oxide (GO)-based and reduced graphene oxide (RGO)-based materials have been utilized in electrochemical biosensors to improve their conductivity for the detection of RAC.…”
