There is an increase of pathogenic multidrug-resistant bacteria globally due to the misuse antibiotics. Recently, more scientists used metal nanoparticles counteract antibacterial resistance. In this study, orange peel waste (OPW) was for selenium nanoparticles' (Se-NPs) biosynthesis through green and ecofriendly method, their applications as antibiofilm agents. Green biosynthesized Se-NPs were characterized using FTIR, XRD, SEM, EDAX, TEM. Characterization results revealed that highly...
The purpose of this study is to create chitosan-stabilized silver nanoparticles (Chi/Ag-NPs) and determine whether they were cytotoxic also their characteristic antibacterial, antibiofilm, wound healing activities. Recently, the development an efficient environmentally friendly method for synthesizing metal based on polysaccharides has attracted a lot interest in field nanotechnology. Colloidal Chi/Ag-NPs are prepared by chemical reduction ions presence Chi, giving Chi/Ag-NPs. Physiochemical...
Currently, nanoparticles and nanomaterials are widely used for biomedical applications. In the present study, silver (AgNPs) were successfully biosynthesized using a cell-free extract (CFE) of Bacillus thuringiensis MAE 6 through green ecofriendly method. The size AgNPs was 32.7 nm, their crystalline nature confirmed by XRD, according to characterization results. A surface plasmon resonance spectrum obtained at 420 nm. Nanoparticles further characterized DLS FTIR analyses, which provided...
Abstract Background and objectives Microbial cells capability to tolerate the effect of various antimicrobial classes represent a major worldwide health concern. The flexible multi-components nanocomposites have enhanced physicochemical characters with several improved properties. Thus, different biological activities biosynthesized starch/silver-selenium nanocomposite (St/Ag-Se NC) were assessed. Methodology St/Ag-Se NC was using Cladosporium cladosporioides CBS 174.62 ( C. ) strain. shape...
Nanoparticles (NPs) and nanomaterials (NMs) are now widely used in a variety of applications, including medicine, solar energy, drug delivery, water treatment, pollution detection. Hematite (α-Fe2O3) nanoparticles (Hem-NPs) were manufactured this work by utilizing cost-effective ecofriendly approach that included biomass filtrate A. niger AH1 as bio-reducer. The structural optical properties Hem-NPs investigated using X-ray diffraction (XRD), transmission electron microscopy (TEM), dynamic...
