Antimicrobial activity of metal oxide microspheres: an innovative process for homogeneous incorporation into materials

“…; Dobrucka ; Salarbashi et al . ). Problems encountered are linked to the hydrophily of the particles and, when used under nanoparticles, their agglomeration and nonhomogeneous repartition, meaning nonhomogeneous availability of active molecules.…”

“…Additional analyses need to be done to clarify the mechanism and the interesting antiviral activity observed in our study. ZnO has multiple applications such as preservative agent, but only a few concerned antimicrobial surfaces (de Rancourt et al 2013;Dobrucka 2014;Salarbashi et al 2016). Problems encountered are linked to the hydrophily of the particles and, when used under nanoparticles, their agglomeration and nonhomogeneous repartition, meaning nonhomogeneous availability of active molecules.…”

“…; Salarbashi et al . ). The aim of using such molecules, and in particular metal oxides, is a large antimicrobial spectrum of activity (Jin et al .…”

“…Numerous assays concerning the adsorption, coating or covalent link of antibiotics to surfaces have been performed (Oprea et al 2016), but this way is now considered a misuse given the increased risk of antibiotic resistance emergence as indicated in the French national alert plan on antibiotics (Minist ere de l'Emploi du Travail et de la Sant e 2011) as well as the United States national antimicrobial resistance monitoring system (NARMS) integrated report proposed for combating antibiotic-resistant bacteria (FDA CDC and USDA 2015). Among other antimicrobial molecules, metallic cations and metal oxides are frequently suggested like copper or alloys (Harrasser et al 2015), silver (Sondi and Salopek-Sondi 2004), magnesium oxide (He et al 2016), zinc oxide under coatings, grafted or integrated in nanoparticles (Jin et al 2009;de Rancourt et al 2013;Pasquet et al 2014;Elkady et al;Pasquet et al 2015;Oprea et al 2016;Salarbashi et al 2016). The aim of using such molecules, and in particular metal oxides, is a large antimicrobial spectrum of activity (Jin et al 2009;Pasquet et al 2014Pasquet et al , 2015, but also the frequent proof of no or poor toxic effect for humans, and sometimes improvement of wound healing and/or epithelialization (Petrochenko et al 2013;Pati et al 2014).…”

Starch-protein active films for food preservation

“…The inclusion of antimicrobial agents in polymer matrices to develop antimicrobial packaging is a promising strategy with which (Salarbashi et al, 2016) to fight both spoilage microorganisms, mainly responsible for off-odours, off-flavours, texture problems or food discoloration and also pathogenic microorganisms that can affect human health . In this sense, Starch/Gelatin blend films incorporated with ethyl lauroyl arginate (N-α-lauroyl-l-arginine ethyl ester monohydrochloride, LAE) have been proven to exhibit antilisterial activity in in vitro tests .…”
