Here, we synthesized a Schiff base, which initially formed a complexation with Cu²⁺ and made Cu⁰ nanoparticles after 8 h aging. In that reaction mixture, addition of Ag⁺ resulted in Ag⁰ nanoparticles. Emissive semi-carbazone (a Schiff base synthesized from semicarbazide and salicylaldehyde) was employed for the first time to selectively and sensitively detect Cu²⁺ (linear range of detection 10^–4 to 5 × 10^–8 M and limit of detection 13 μM) with the formation of copper oxide nanoparticles via complexation–reduction method. The introduction of Ag⁺ in it produced Ag⁰ and Cu⁰ (CuO via aerial oxidation) nanoparticles with a gigantic increase of fluorescence to obtain selective and sensitive Ag⁺ detection (linear detection range 10^–3–10^–7 M, and limit of detection 7. 7 μM). Thus, Cu²⁺ and Ag⁺ were detected based on turn-off/on fluorescence in one pot. As the evolution of copper and silver nanoparticles was the fundamental reason for sensing, response time is similar to the stable fluorescence behavior of oxidized SC (capping agent) with in situ generated copper and silver nanoparticles. CuO-induced fluorescence quenching was due to the formation of the trapped plasmon, while Ag⁺-induced fluorescence enhancement was owing to the lightning rod effect. The synergism of Cu and Ag was also investigated in this paper as a driving force of the lightning rod effect for the first time. Both the metals (Cu and Ag) were estimated in natural water, justifying the utility of the sensing platform for practical applications. Besides, the evolution of brilliant red color with semi-carbazone for Ag⁺ was employed for the colorimetric sensing of Ag⁺.</p></div>","PeriodicalId":471,"journal":{"name":"Applied Nanoscience","volume":"14 5","pages":"739 - 751"},"PeriodicalIF":3.674,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140581274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These N-CQDs exhibited remarkable and dynamic “on-off-on” luminescent characteristics, demonstrating an exceptional sensitivity and selectivity towards tannic acid and Hg²⁺ ions. The specific interactions between the N-CQDs and tannic acid, along with the reversible binding with Hg²⁺ ions, contribute to the distinct dual-detection capabilities. The sensing system covers a linear concentration range of 10–80 µM to tannic acid and 0.1 to 1 nm for Hg²⁺, showcasing its versatility for different concentration range with a lower detection limit of 25 nM and 3 nM, respectively. Furthermore, the N-CQDs displayed high stability and minimal interference from typical interfering species, making them a desirable tool for environmental monitoring and quality control. Validation through real sample analysis substantiates the accuracy and reliability of the developed sensing approach in practical scenarios.

This study presents a pioneering approach to synthesize superparamagnetic magnetite nanoparticles (SM-NPs) derived from natural ore using an environmentally friendly, green chemistry approach. These SM-NPs exhibit exceptional magnetic properties, surpassing all other forms of iron oxide, making them a novel and promising multi-imaging agent for various biomedical applications. The SM-NPs were synthesized with high purity from naturally occurring magnetite, sourced from the Earth's crust. Characterization via X-ray diffraction (XRD) confirmed the cubic spinel ferrites structure of the sample, with an average particle size of 21.24 nm. Fourier-Transform Infrared Spectroscopy (FT-IR) revealed the presence of elemental functional groups, further supporting the material's suitability for biomedical use. Morphological analysis using field emission scanning electron microscopy with energy-dispersive X-ray analysis (FESEM-EDX) unveiled agglomerated spherical particles ranging in size from 60 to 80 nm. The elemental composition analysis via EDX demonstrated predominant iron (Fe) and oxygen (O) elements at concentrations of 75.55% and 20.76%, respectively. The magnetic properties of the SMNPs were assessed using a vibrating sample magnetometer (VSM), revealing a superparamagnetic behavior, as evidenced by the M-H plot. Furthermore, X-ray imaging exhibited a significant signal, even with just 40 mg of the substance, suggesting its potential as a robust contrast agent. Complementary findings from computed tomography (CT) and magnetic resonance imaging (MRI) scans demonstrated substantial absorption capabilities, even at relatively low concentrations of SM-NPs. These remarkable attributes position the green-synthesized SM-NPs as a highly versatile and efficient multi-imaging agent for various biomedical applications.

Here, we have endeavored to synthesize starch encapsulated CuNPs through radiation chemical approach which is considered to be one of the cleanest routes and involve <i>in-situ</i> generated hydrated electrons to reduce metal ions directly.
