Bioinorganic Chemistry and Applications 24/01/16 Nanosilver Biocidal Properties and Their Application in Disinfection of Hatchers in Poultry Processing Plants.

The aim of this study was to use aqueous suspensions of silver nanoparticles with a wide spectrum of particle sizes, variable morphology, high stability, and appropriate physicochemical properties to examine their bactericidal and fungicidal properties against microorganisms present in poultry processing plants.

At the same time, the particles were tested for preventing the production of odorogenous pollutants during incubation and thereby reducing the emission of harmful gases from such types of facilities. The results show that the use of nanosilver preparations in order to disinfect eggs and hatchers reduced microbiological contamination. PARLEMENT EUROPEEN - Réponse à question E-003977-18 Silver nanoparticles replacing antibiotics in chicken-farming. The abuse of antibiotics in intensive farming and the increasingly frequent warnings about antimicrobial resistance have prompted researchers from all over the world to look for alternative solutions.

One of the options being proposed is silver nanoparticles, although there are as yet no studies on their safety. That was why the Venezie Experimental Zooprophylactic Institute (IZSV) sought to understand whether they might entail risks to consumers; its study has been published in the Journal of Agricultural and Food Chemistry.

A variety of material production processes occur at nanometer length scales. Such as, textile silver nanoparticles antimicrobial activity (9), gold nanoparticles super catalase activity and most nanoparticles offer some unique advantages as sensing, delivery, and image enhancement agents in medicine (6, 7, 8). Due to different fabrication methods, such many varieties of nanoparticles were available: polymeric nanoparticles, dendrimers, metal nanoparticles, quantum dots, liposomes, micelles and other types of nano-assemblies (1, 2, 5). Most of these nanostructures could be applied onto life science application, especially in medical disease diagnosis and therapy (4, 6).

FREE PATENT - LATEX ARTICLES CONTAINING NANO-SILVER AND THE PREPARATION THEREOF

Ancient or modern, in China or abroad, when human recognition of the natural world was still in the days in which the heaven was considered as round and the earth as flat and square, when human beings were still in the days in which they lacked scientific knowledge of silver but only had visual and perceptual knowledge that resulted from frequent access to and use of various silver coins and silver products in daily life, they already began to use silver ware and silver foil for treatment of diseases and injuries or even used them as health protection medicine.

In life, silver is often used to keep fresh and preserve water and food, and to treat injuries and cure wounds in war. Silver is off-white powder, is a relatively stable substance, is basically insoluble in water, in hydrochloric acid and in alkali; and its own bactericidal power is not strong. AZONANO 16/08/06 Silver Nanoparticles – How They Are Providing Environmentally Friendly Antibacterial Properties In Consumer Goods. The antibacterial property of silver has been known for thousands of years with the ancient Greeks cooking from silver pots and the old adage ‘born with a silver spoon in his mouth’ referring to more than just wealth.

AZONANO 16/08/06 Silver Nanoparticles – How They Are Providing Environmentally Friendly Antibacterial Properties In Consumer Goods

Eating with a silver spoon was known to be more hygienic. Manufacturing entire objects from pure silver metal or coating them with silver is prohibitively expensive for consumer items but research has found that impregnating other materials with silver nanoparticles is a practical way to exploit the germ fighting properties of silver. How Silver Nanoparticles Work The extremely small size of nanoparticles means they exhibit enhanced or different properties when compared with the bulk material. The extremely small size of nanoparticles results in the particles having a large surface area relative to their volume.

SCIENCE DAILY 30/04/08 Silver Nanoparticles May Be Killing Beneficial Bacteria In Wastewater Treatment

For years, scientists have known about silver's ability to kill harmful bacteria and, recently, have used this knowledge to create consumer products containing silver nanoparticles. Now, a University of Missouri researcher has found that silver nanoparticles also may destroy benign bacteria that are used to remove ammonia from wastewater treatment systems.

Une équipe du M.D Anderson Medical Center à Houston étudie l'association de nanoparticules d'or avec des virus en vue d'applications thérapeutiques. Le but est de créer un réseau moléculaire bioactif constitué de bactériophages (virus qui infectent seulement les bactéries) assemblés aux nanoparticules d'or. Les phages génétiquement modifiés portent sur leur membrane des peptides qui se lient spécifiquement aux molécules cibles. USINE NOUVELLE 16/10/06 Des nanoparticules d'argent contre les microbes.

LES NOUVELLES 23/03/10 Nanomatériaux : principe de précaution contre chaussettes anti-odeurs

C'est l'avis que vient de rendre l'Afsset (Agence française de sécurité sanitaire de l'environnement et du travail). Alors que les nanomatériaux, ces particules aux propriétés innovantes, ont envahi des centaines de produits de consommation quotidiens, l'Afsset met en garde contre les risques pour la santé et pour l’environnement que pourraient impliquer ces matériaux, encore trop mal étudiés. L'étude de l’Afsset publiée mardi 24 mars, vient mettre son grain de sel dans le débat sur les nanotechnologies. Le débat public sur le même thème, qui s'est clôturé tout juste un mois avant, et dont les conclusions sont… La suite de cet article est accessible sur abonnement.
