Research ArticleOpen accessEvery word in the titleCytocompatibility and Antimicrobial Properties of Silver Nanoparticles-Loaded AMPs in the Oral CavityYanli Lv, Weikai ZhangPostoperative infection following oral metal implantation is a key factor that affects the success rate of surgery. This infection is mainly caused by bacterial biofilms. Traditional single antibacterial coatings have limitations, including a narrow antibacterial spectrum and poor cytotoxicity or stability. This study combined silver nanoparticles (AgNPs) and the synthetic antimicrobial peptide GL13K using electrostatic self-assembly technology to create a … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 24 Apr 2026 · 1,685 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGreen Synthesis of Silver Nanoparticles using Extract of Disporopsis Longifolia for Photocatalytic Degradation of Methylene BlueKhieu Thi Tam, Dang Van Thanh, Huu Tap Van et al.In this report, the silver Nanoparticles (AgNPs)were successfully synthesized in a simple one-pot method by the leaf and stemextract of Disporopsis longifolia as reducing, capping agents, andstabilizers for the first time. The optimal extract amount, AgNO3concentration, reaction temperature, and time for the AgNPs synthesis wereidentified using Ultraviolet-Visible (UV-Vis) spectroscopy. X-Ray Diffraction (XRD)and Scanning Electron Microscopy (SEM) were used to characterize … …American Journal of Environmental Sciences, Vol. 18, Issue 5 · 23 Nov 2022 · 6,563 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBiogenic Silver Nanoparticles Produced by Bacteria Isolated from University Campus Environment Soil Samples in Ras Al KhaimahPooja Shivappa, Grisilda Vidya Bernhardt, Sheela Haridas, Michael V MagaogaoSilver is observed to be comprised of a huge percentage ofsilver oxide and the utilization of silver and silver salts is in practicesince ancient human civilization. Silver nanoparticles remain to be potentialantifungal, antibacterial, anti-inflammatory, and antiviral agents. Further, itis demonstrated that silver nanoparticles have been involved in arresting thegrowth of several bacterial species thereby reducing their harmful effects.Micro-organisms are being … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 5 Sep 2022 · 5,870 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleProtective Role of Chichorium intybus Extract Against Renal Toxicity Induced by Magnetite Silver Nanoparticles in Male RatsDoha M. Beltagy, Ehab Tousson, Nabiha I Abdo, Batoul M. IzzularabMagnetite silver nanoparticles (Fe3O4/AgNPs) symbolize a new candidate in several industrial and biological products for their activities, simple preparation and low synthesis costs. Many studies recommended the usage of Fe3O4/AgNPs to overcome lacking biocompatibility of AgNPs inside the body. However, Fe3O4/AgNPs also has toxic effects on kidney tissues. In this study, AgNPs was synthesized on the surface of magnetic nanoparticles … …OnLine Journal of Biological Sciences, Vol. 21, Issue 3 · 15 Sep 2021 · 6,318 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleMechanistic Insights of Actions of Metal Nanoparticles on Multidrug-Resistant BacteriaSeham S. Alzahrani, Hani Mohammed Ali, Mohamed M. AhmedMultidrug-Resistant bacteria (MDR) are the most serious threat to public health. The number of infections caused by resistant strains is on the rise all over the world. At this time, new techniques for developing antimicrobial drugs are becoming necessary. Metallic Nanoparticles (MNPs) in the biomedical field are one of the most promising methods to overcome antibiotic resistance. Nanoparticles have recently … …OnLine Journal of Biological Sciences, Vol. 21, Issue 2 · 22 Jun 2021 · 6,374 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSafe Ulvan Silver Nanoparticles Composite Films for Active Food PackagingHadear Hanie AminProtecting food from the corruption caused by different microbes is a big problem, as we need safe methods for food packaging. In this study, Ulvan (U), edible sulfated polysaccharide extracted from Ulva lactuca, was mediated for the first time non-toxic biosynthesized silver nanoparticles (Ag-NPs) to produce new and safe bio-nanocomposite films called (U/Ag-NPs) films for active food packaging. Ulvan was … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 28 Jan 2021 · 7,740 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAssessment of the Toxic Effects of Chitosan-Coated Magnetite Nanoparticles on Drosophila melanogasterDoris Vela, Jonathan Rondal, Sofía Cárdenas et al.Nanoparticles are a cause for concern because of their potential toxic effects on human health and the environment. The aim of this study was to assess the toxic effect of chitosan-coated magnetite nanoparticles (11.00±4.7 nm) on Drosophila melanogaster through the observation of hemolymph composition, DNA damage, larval survival and lifespan of flies. Chitosan-coated magnetite nanoparticles were synthesized by co-precipitation method. … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 25 Sep 2020 · 7,882 accessesView PDFCite
