In this study, the development of a graphite paste electrode (GPE) modified by copper oxide nanoparticles (CuO@GP) to be used as a practical and economical sensor for the electrochemical sensing of malachite green (MG) has been elucidated. The sol–gel technique was applied for the synthesis of CuO nanoparticles (NPS) from copper chloride (CuCl[Formula: see text], where the surfactant cetylpyridinium chloride (C[Formula: see text]H[Formula: see text]NCl) played the role of a capping agent. The synthesized CuO NPS were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). A bare GPE was modified using these CuO NPS and thus developed; the new electrode was used as a working electrode (WE) in a 3-electrode system for studying the cyclic voltammetry (CV) and differential pulse voltammetry (DPV) responses of MG. Phosphate buffered saline (PBS) with a pH value of 6 was used as the optimum buffer. Using DPV, a widely linear operational range of 1–1000 [Formula: see text]M was obtained with a detection limit of 0.18 [Formula: see text]M. This CuO@GP provided excellent repeatability, reproducibility and prolonged stability for the MG molecule. For the selectivity study, various common interfering agents were used to observe MG’s corresponding peak current variation. Moreover, this electrode demonstrated a successful application for detecting MG in pond water and fish flesh. This method is effective for similar other applications.

This study was based on the hypothesis that spatial–temporal characterization of contaminant-affected redox gradients in a quiescent system could be measured by microbial potentiometric sensor (MPS) arrays incorporated in large, natural biofilm networks. Two experimental chambers, each containing at least 48 equidistantly located MPS electrodes, were fabricated to examine reproducibility of the patterns. The MPS electrodes were exposed to biofilm growth conditions by introducing high dissolved organic carbon (DOC) and dechlorinated tap water at the bottom of the experimental chamber; and the spatial–temporal changes in the MPS array signals were recorded, which showed that signal trends were correlated to the induced changes in DOC. The results indicated that MPS arrays measured the spatial–temporal changes in the aqueous solution caused by an influx of carbon rich water, which could not be detected by conventional oxidation-reduction potential (ORP) electrodes. Interestingly, the experiments conducted over long time periods revealed unusual behaviors like electrical signaling and possible potentiometrically driven communication within the biofilm. These observed behaviors suggest that biofilms may create a large network through which communication signals can be generated and propagated by inducing changes in electric potentials similar to a sophisticated electronic device.

Selenium nanoparticles have drawn interest recently, due to their distinctive physicochemical characteristics and potential usage in numerous applications, including medicine, electronics and catalysis. In this study, we employed Biancaea sappan (BS), often known as sappan wood or Brazilwood, which is a flowering tree that is endemic to Southeast Asia. Due to its antioxidant, anti-inflammatory and anticancer properties, this tree’s heartwood is frequently used in traditional medicine. Additionally, the wood is used to make natural dyes. In this study, we aim to develop an ecofriendly selenium nanoparticle using BS, as a natural reducing agent and curcumin as a capping agent. The nanoparticles were synthesized using the green synthesis method and characterized using various techniques. Biocompatibility was evaluated using hemolytic assay and the bioactivity of the nanoparticles was assessed using anti-inflammatory and antioxidant assays. Selenium nanoparticles (BCSeN) were successfully synthesized using BS bark extract and functionalized with curcumin. The nanoparticles were characterized by UV-Vis Spectroscopy, X-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscopy and Energy-dispersive X-ray spectroscopy (EDX) analysis, confirming their morphology, crystallinity, functionalization, elemental composition, size and stability. In vitro, bioactivity studies revealed that the BCSeN exhibited significant anti-inflammatory activity. They also demonstrated notable antioxidant efficacy against DPPH (2,2-diphenyl-1-picrylhydrazyl) and were also found to have minimal hemolytic potential. Our findings highlight the potential of BCSeN as a promising candidate for anti-inflammatory and antioxidant applications. However, further in-depth analysis is required to fully understand their efficacy and toxicity.
