Abstract Extracellular production of metal nanoparticles by several strains the fungus Fusarium oxysporum was carried out. It found that aqueous silver ions when exposed to are reduced in solution, thereby leading formation hydrosol. The were range 20–50 nm dimensions. reduction occurs a nitrate-dependent reductase and shuttle quinone extracellular process. potentialities this nanotechnological design based fugal biosynthesis for technical applications important, including their high...
Microorganisms play an important role in toxic metal remediation through reduction of ions. Studies demonstrated that silver ions may be reduced extracellularly using Fusarium oxysporum to generate stable gold or nanoparticles water. These particles can incorporated several kinds materials such as cloths. cloths with are sterile and useful hospitals prevent minimize infection pathogenic bacteria Staphylococcus aureus. In this work, the extracellular production by F. its antimicrobial effect...
The antimicrobial properties of silver have been known for thousands years. Recently, nanoparticles gained attention because their activity which offers the possibility use medical and hygiene purposes. Indeed, in different formulations with shapes sizes exhibit variable activity. However, mechanisms ions nanoparticles, toxicity to human tissues are not fully characterized. This review evaluates potential control pathogens emphasis on action against pathogenic bacteria, possible action.
Introduction: Cell-based assays using three-dimensional (3D) cell cultures may reflect the antitumor activity of compounds more accurately, since these models reproduce tumor microenvironment better. Methods: Here, we report a comparative analysis behavior in two most widely employed methods for 3D spheroid culture, forced floating (Ultra-low Attachment, ULA, plates), and hanging drop (HD) methods, RT4 human bladder cancer line as model. The morphology parameters growth/metabolism spheroids...
Abstract Gold nanoparticles (AuNPs) are highlighted due to their low toxicity, compatibility with the human body, high surface area volume ratio, and surfaces that can be easily modified ligands. Biosynthesis of AuNPs using plant extract is considered a simple, low-cost, eco-friendly approach. Brazilian Red Propolis (BRP), product bees, exhibits anti-inflammatory, anti-tumor, antioxidant, antimicrobial activities. Here, we described biosynthesis BRP (AuNP ) its fractions hexane , AuNP...
The skin is a critical organ for the maintenance of integrity and protection organism. When wound occurs, sequence healing mechanisms triggered to reconstruct wounded area. β-caryophyllene sesquiterpene in Copaifera langsdorffii oleoresin with antioxidant anti-inflammatory potential. On basis previous studies C. langsdorffii, was selected evaluate its potential pharmacological mechanisms. excision model used male Wistar rats macroscopic, histological, immunohistochemical biochemical analyses...
The demand for food production has been growing exponentially due to the increase in global population. Innovative approaches enhance agricultural productivity have explored, including new applications of nanoparticles agriculture. nanoparticle application agriculture can generate environmental and human health risks since contaminate soil inevitably reach groundwater, potentially causing toxicity aquatic organisms. In this study, we evaluated benefits gold (GNPs), synthesized via green...
Silver nanoparticles (AgNPs) have been extensively studied because of their anti-microbial potential. Here, we evaluated the effect biologically synthesized silver (AgNP bio ) alone and in combination with fluconazole (FLC) against planktonic cells biofilms FLC-resistant Candida albicans . AgNP exhibited a fungicidal effect, minimal inhibitory concentration (MIC) ranging from 2.17 to 4.35 μg/ml. The FLC reduced MIC around 16 64 times all C. There was no significant on biofilm cells. However,...
Plant pathogenic fungus Fusarium culmorum (MTCC-2090) assists in the mycosynthesis of silver nanoparticles. Formation spherical nanoparticles was confirmed from TEM analysis and found range 5-25 nm with an average diameter 11 nm. Different temperature pH affects synthesis indicating that depends significantly on pH. at room pH-7 to be optimum for process. The combined effects mycosynthesized different antibiotics like kanamycin, erythromycin, oxacillin, tetracycline, vancomycin gentamycin...
Development of nanobiosensor is one the most recent advancement in field Nanotechnology. Research on optical nanobiosensors with submicron-sized dimensions has opened new horizons for intracellular measurements. Taking advantage unique properties nanomaterials, faster and sensitive can be developed. Apart from being fast, studies related to have geared their efforts towards development nanomaterial-based sensors that are affordable, robust reproducible. The equipped immobilized bioreceptor...
