“…High‐performance ion chromatography and ion‐pair liquid chromatography are good optional methods; however, they need the high cost to buy columns and waste more organic solvents. Furthermore, most of the mentioned analytical methods are very complicated pre‐concentration, time‐consuming steps, and high‐cost instruments and restrict the application of the existing methods . Among these methods, the electrochemical techniques develop a simple, fast, low cost and operative method for the analysis of nitrite.…”

“…Furthermore, most of the mentioned analytical methods are very complicated pre-concentration, time-consuming steps, and high-cost instruments and restrict the application of the existing methods. [25] Among these methods, the electrochemical techniques develop a simple, fast, low cost and operative method for the analysis of nitrite. However, the large over potential of the reduction of nitrite confines the application of the electrochemical approach for its determination at the surface of the bare solid electrodes.…”

Here, a green method is described for the biosynthesis of Ag nanoparticles (Ag NPs) using aqueous extracts of the leaf of Salvia leriifolia as reducing and stabilizing agent. Various techniques such as scanning electron microscopy (SEM), atomic force microscopy (AFM), transmission electron microscopy (TEM) and X‐ray diffraction (XRD) were employed for the characterization of the structure and morphology of bio‐synthesized AgNPs. The results reveal that AgNPs synthesized with uniform spherical morphology and average diameters of 27 nm. The AgNPs as a green and efficient heterogeneous catalyst presented superior antibacterial activity. Direct electrochemistry studies of the synthesized AgNPs confirmed that nanoparticles retained their direct electrochemical activity. This is mainly attributed to the proper biosynthesis process, the large specific surface area and the good conductivity of the synthesized nanoparticles. Hence, the present synthesized AgNPs displayed good electrocatalytic activity to the reduction of nitrite ions. The proposed method is highly recommended as a novel platform for the development of electrochemical sensors which can further expand the applications of AgNPs. Antibacterial activity of the synthesized AgNPs was evaluated against nine microorganisms. AgNPs prevented the growth of all selected bacteria. The nanoparticles inhibited the growth of Pseudomonas aeruginosa, Klebsiella pneumonia, Staphylococcus coagulase, Acinetobacter baumannii, and Streptococcus pneumonia more than antibiotic of vancomycin, however, the ability of AgNPs against Echerishia coli and Serratia marcescens was less than the antibiotic. On the other hand AgNPs were active against Citrobacter frurdii, while the antibiotic was inactive.

“…The linear melamine detection concentration was from 0.1 to 30 µM with a LOD of 29.3 nM. Rovina et al described an electrochemical sensor composed of ionic liquid/zinc oxide nanoparticles/chitosan/gold electrode for melamine identification [85]. The authors used the (1-ethyl-3-methylimidazolium tri-fluoromethanesulfonate ([EMIM][Otf])) as ionic liquid, ZnO nanoparticles, chitosan nanocomposite membranes and gold electrode for melamine assay.…”

Illegal adulteration of milk products by melamine and its analogs has become a threat to the world. In 2008, the misuse of melamine with infant formula caused serious effects on babies of China. Thereafter, the government of China and the US Food and Drug Administration (FDA) limited the use of melamine of 1 mg/kg for infant formula and 2.5 mg/kg for other dairy products. Similarly, the World Health Organization (WHO) has also limited the daily intake of melamine of 0.2 mg/kg body weight per day. Many sensory schemes have been proposed by the scientists for carrying out screening on melamine poisoning. Among them, nanomaterial-based sensing techniques are very promising in terms of real-time applicability. These materials uncover and quantify the melamine by means of diverse mechanisms, such as fluorescence resonance energy transfer (FRET), aggregation, inner filter effect, surface-enhanced Raman scattering (SERS), and self-assembly, etc. Nanomaterials used for the melamine determination include carbon dots, quantum dots, nanocomposites, nanocrystals, nanoclusters, nanoparticles, nanorods, nanowires, and nanotubes. In this review, we summarize and comment on the melamine sensing abilities of these nanomaterials for their suitability and future research directions.

“…A maioria das técnicas usuais para o diagnóstico molecular de leucemia apresentam limitações de custo e tempo, tais como a PCR e FISH. Tendo isto em vista, o desenvolvimento de biossensores eletroquímicos vêm ganhando espaço na área de diagnósticos clínicos por apresentarem alta sensibilidade, seletividade e resposta analítica rápida com baixo custo (SHARMA et al, 2012;ROVINA;SIDDIQUEE, 2016). Os biossensores são constituídos por uma camada biológica responsável por detectar o analito, ligada a um transdutor, que transforma o sinal da interação biomolecular em uma resposta quantificável; logo depois, esta resposta é amplificada em um processador eletrônico e convertida em gráficos (FRÍAS et al, 2015).…”
