The petroleum-based materials could be replaced, at least partially, by biodegradable packaging. Adding antimicrobial activity to the new packaging can also help improve shelf life of food and diminish spoilage. objective this research was obtain a novel antibacterial packaging, based on alginate as polymer. induced films adding various amounts ZnO nanoparticles loaded with citronella (lemongrass) essential oil (CEO). obtained were characterized, tested against two Gram-negative (Escherichia...
Replacing the petroleum-based materials in food industry is one of main objectives scientists and decision makers worldwide. Biodegradable packaging will help diminish environmental impact human activity. Improving such biodegradable by adding antimicrobial activity not only extend shelf life foodstuff, but also eliminate some health hazards associated with borne diseases, diminishing spoilage decrease waste. The objective this research was to obtain innovative antibacterial films based on a...
Zinc oxide (ZnO) nanomaterials are used in various health-related applications, from antimicrobial textiles to wound dressing composites and sunscreens packaging. Purity, surface defects, size, morphology of the nanoparticles main factors that influence properties. In this study, we comparing properties ZnO obtained by solvolysis using a series alcohols: primary methanol 1-hexanol, secondary (2-propanol 2-butanol), tertiary (tert-butanol). While synthesis is successfully accomplished all...
As it is used in all aspects of human life, water has become more and polluted. For the past few decades, researchers scientists have focused on developing innovative composite adsorbent membranes for purification. The purpose this research was to synthesize a novel membrane removal toxic pollutants (namely heavy metals, antibiotics microorganisms). as-synthesized chitosan/TiO2 were successfully prepared through simple casting method. TiO2 nanoparticle concentration from kept low, at 1% 5%,...
In this paper, we report the synthesis of ZnO nanoparticles (NPs) by forced solvolysis Zn(CH3COO)2·2H2O in alcohols with a different number -OH groups. We study influence alcohol type (n-butanol, ethylene glycol and glycerin) on size, morphology, properties obtained NPs. The smallest polyhedral NPs (<30 nm) were n-butanol, while measured average 44 nm rounded. Polycrystalline particles 120 glycerin only after water refluxing. addition, here, photocatalytic activity, against dye mixture,...
One major problem with the overuse of antibiotics is that microorganisms acquire resistance; thus dose must be increased unsustainably. To overcome this problem, researchers from around world are actively investigating new types antimicrobials. Zinc oxide (ZnO) nanoparticles (NPs) have been proven to exhibit strong antimicrobial effects; moreover, Food and Drugs Administration (FDA) considers ZnO as GRAS (generally recognized safe). Many essential oils activity their components do not...
: Cellulose derivatives are gaining much attention in medical research due to their excellent properties such as biocompatibility, hydrophilicity, non-toxicity, sustainability, and low cost. Unfortunately, cellulose does not exhibit antimicrobial activity. However, like hydroxyethyl represent a proper matrix incorporate agents with beneficial therapeutic effects.
New packaging materials based on biopolymers are gaining increasing attention due to many advantages like biodegradability or existence of renewable sources. Grouping more antimicrobials agents in the same can create a synergic effect, resulting either better antimicrobial activity against wider spectrum spoilage lower required quantity antimicrobials. In present work, we obtained biodegradable film that be used as material for food. Films chitosan polymer, with ZnO and Ag nanoparticles...
In this study, zinc oxide nanoparticles were synthesized through a simple co-precipitation method starting from acetate dihydrate and sodium hydroxide as reactants. The as-obtained ZnO morphologically structurally characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM), photocatalytic activity, determining the antimicrobial activity against Gram-negative Gram-positive bacteria. XRD pattern of showed...
The synthesis of nanoparticles from noble metals has received high attention researchers due to their unique properties and wide range applications. Silver (AgNPs), in particular, show a remarkable inhibitory effect against microorganisms viruses. Various methods have been developed obtain AgNPs, however the stability such nanostructures over time is still challenging. Researchers attempt particular shapes sizes order tailor AgNPs for specific areas, as biochemistry, biology, agriculture,...
