Druck auf Anfrage Neuware - Printed after ordering - Scientific Study from the year 2018 in the subject Biology - Micro- and Molecular Biology, grade: 1, , language: English, abstract: Conventional synthesis of nanoparticles chemically releases toxic byproducts so there was a sudden shift towards the synthesis of nanoparticles through biological methods as it was assumed that biosynthesized nanoparticles would not be toxic. The present study aims at comparative toxicity analysis of chemically and biologically synthesized copper oxide and silver nanoparticles. Biologically synthesized copper oxide and silver nanoparticles were subjected to antimicrobial activity against five bacterial species at different dilution rate (20%, 50%, 70% and 100%). The result obtained for this was that for silver nanoparticles synthesized chemically E.coli was susceptible at 20% and 50% dilution rate. At 70% dilution rate for copper oxide nanoparticles synthesized chemically two bacterial species i.e. E.aerogens and P.aeroginosa were highly susceptible but other three species were susceptible.

Add to basketTaschenbuch. Condition: Neu. Neuware -Iron nanoparticles were effectively created in an efficient, rapid, simple, and inexpensive method by reducing Iron chloride solution with banana peel extract. Because of this, the trash from banana peels utilised to produce iron nanoparticles was successfully recycled. Synthesized Iron nanoparticles were examined using FTIR, XRD, UV- Vis, TEM, and SEM methods in addition to visual inspection by colour changing. Iron nanoparticle formation was verified by the presence of blackish-brown colour in the ferric chloride and BPE reaction mixture. TEM images showed that the nanoparticles were granular in shape and had diameters between 20 and 50 nanometers. Strong iron signals were seen in EDS at energies of 182, 215, 424, and 458, suggesting the synthesis of Fe nanoparticles. Furthermore, the iron nanoparticles were studied using x-ray diffraction, and it was discovered that they are characteristic of crystal planes (110), (200), and (112). Following their synthesis and purification, FeNPs can be employed in biological and biomedical applications such as drug delivery vehicles, novel aptamer-established biosensing assays, and microcystin detection sensors.Books on Demand GmbH, Überseering 33, 22297 Hamburg 60 pp. Englisch.

Add to basketTaschenbuch. Condition: Neu. Neuware -Eisen-Nanopartikel wurden in einer effizienten, schnellen, einfachen und kostengünstigen Methode durch Reduktion von Eisenchloridlösung mit Bananenschalenextrakt hergestellt. Dadurch konnte der Abfall von Bananenschalen, der zur Herstellung von Eisennanopartikeln verwendet wurde, erfolgreich recycelt werden. Die synthetisierten Eisennanopartikel wurden mit Hilfe von FTIR-, XRD-, UV-Vis-, TEM- und SEM-Methoden untersucht, zusätzlich zur visuellen Inspektion durch Farbveränderung. Die Bildung von Eisennanopartikeln wurde durch das Vorhandensein einer schwarz-braunen Farbe in der Reaktionsmischung aus Eisenchlorid und BPE nachgewiesen. TEM-Bilder zeigten, dass die Nanopartikel eine körnige Form und einen Durchmesser zwischen 20 und 50 Nanometern hatten. Bei der EDS wurden starke Eisensignale bei Energien von 182, 215, 424 und 458 festgestellt, was auf die Synthese von Fe-Nanopartikeln hindeutet. Darüber hinaus wurden die Eisennanopartikel mit Hilfe der Röntgenbeugung untersucht, und es wurde festgestellt, dass sie für die Kristallebenen (110), (200) und (112) charakteristisch sind. Nach ihrer Synthese und Reinigung können FeNPs in biologischen und biomedizinischen Anwendungen eingesetzt werden, z. B. als Vehikel für die Verabreichung von Arzneimitteln, als neuartige Aptamer-gestützte Biosensortests und als Sensoren zum Nachweis von Microcystin.Books on Demand GmbH, Überseering 33, 22297 Hamburg 56 pp. Deutsch.
