Enhancing the antimicrobial activity of natural extraction using the synthetic ultrasmall metal nanoparticles

Scientific Reports, Journal Year: 2015, Volume and Issue: 5(1)

Published: June 5, 2015

Abstract The use of Catechin as an antibacterial agent is becoming ever-more common, whereas unstable and easy oxidation, have limited its application. A simple low-energy-consuming approach to synthesize highly stable dispersive Catechin-Cu nanoparticles(NPs) has been developed, in which the stability dispersivity NPs are varied greatly with pH value temperature reaction. results demonstrate that optimal reaction conditions 11 at room temperature. As-synthesized display excellent antimicrobial activity, survival rates bacterial cells exposed were evaluated using live/dead Bacterial Viability Kit. showed concentration 10 ppm 20 provided rapid effective killing up 90% 85% S. aureus E. coli within 3 h, respectively. After treatment 40 NPs, bacteria killed completely. Furthermore, on basis assessing effects by SEM, TEM AFM, it was found cell membrane damage caused direct contact mechanism inactivation.

Abstract A simple, eco-friendly, and biomimetic approach using Thymus vulgaris ( T . ) leaf extract was developed for the formation of ZnO-Ag nanocomposites (NCs) without employing any stabilizer a chemical surfactant. used first time, in novel approach, green fabrication NCs as size based reducing agent via hydrothermal method single step. Presence phenols has served both capping agents that play critical role production NCs. The effect silver nitrate concentration studied. in-vitro Antimicrobial activity displayed high antimicrobial potency on selective gram negative positive foodborne pathogens. Antioxidant evaluated (2,2-diphenyl-1-picrylhydrazyl) DPPH method. Photocatalytic performance appraised by degradation phenol under natural sunlight, which exhibited efficient photocatalytic phenol. Cytotoxicity haemolysis assay. Results this study reveal extract, containing phytochemicals, possess property obtained could be employed effectively biological applications food science. Therefore, present offers promising way to achieve high-efficiency photocatalysis hybrid structure semiconductor/metal.

Characterization of Antimicrobial Poly (Lactic Acid)/Nano-Composite Films with Silver and Zinc Oxide Nanoparticles

Materials, Journal Year: 2017, Volume and Issue: 10(6), P. 659 - 659

Published: June 16, 2017

Antimicrobial active films based on poly (lactic acid) (PLA) were prepared with nano-silver (nano-Ag) and nano-zinc oxide (nano-ZnO) using a solvent volatilizing method. The characterized for mechanical, structural, thermal, physical antimicrobial properties. Scanning electron microscopy (SEM) images the fracture morphology of different contents nano-Ag nano-ZnO. addition nanoparticles into pure PLA film decreased tensile strength elasticity modulus increased elongation breaks—in other words, flexibility extensibility these composites improved. According to results differential scanning calorimetry (DSC), glass transition temperature nano-composite decreased, crystallinity increased; similar result was apparent from X-ray diffraction (XRD) analysis. water vapor permeability (WVP) opacity augmented compared film. Incorporation significantly improved activity inhibit growth Escherichia coli. indicated that could be considered potential environmental-friendly packaging material.
