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.","PeriodicalId":44929,"journal":{"name":"Nano Life","volume":" 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135293268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":44929,"journal":{"name":"Nano Life","volume":" 19","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135293380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":44929,"journal":{"name":"Nano Life","volume":"14 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135728304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Silver (Ag) is an appealing tool in many domains, including diagnosis, medicine delivery, environment, electronics, and as an antibacterial agent. Ag nanoparticle applications are ubiquitous today in the fields of biosensors. Numerous studies have demonstrated the effectiveness of using Ag nanoparticles to improve the specific detection of clinical indicators. The development of nanotechnology has greatly benefited the field of biosensors since nanomaterials have a high surface-to-volume ratio that enables them to operate with greater sensitivity and effectiveness. Utilizing interdisciplinary study in biology, chemistry, and material science, recent advancements in nanotechnology encouraged the manufacture of nanomaterials in a variety of shapes and sizes. In the context of disease diagnosis, this review highlighted the use of Ag nanoparticles in biosensors to detect small molecules to bigger entire cells. This paper also discusses how to make a glucose biosensor more sensitive.
