Hybrids, i.e., intimately mixed polymer/phospholipid vesicles, can potentially marry in a single membrane the best characteristics of two separate components. The ability amphiphilic copolymers and phospholipids to self-assemble into hybrid membranes has been studied until now on submicrometer scale using optical microscopy giant unilamellar vesicles (GHUVs), but limited information is available large (LHUVs). In this work, based poly(dimethylsiloxane) poly(ethylene oxide) with different...
Amphiphilic copolymers with bottlebrush architecture provide opportunities for the refinement of materials properties that may not be attainable from their linear analogues. In this study, we investigated effect polymer on an interplay between molecular packing inside micelle cores, cargo loading, and core cross-linking. Four families polylactide-b-poly(ethylene oxide) (PLA–PEO) block different side-chain arrangements were synthesized by a combination grafting-through grafting-from methods....
Hybrid polymer/lipid large unilamellar vesicles (LUVs) were studied by small angle neutron scattering (SANS), time-resolved Förster resonance energy transfer (TR-FRET), and cryo-transmission electron microscopy (cryo-TEM). For the first time in hybrid vesicles, evidence for phase separation at nanoscale was obtained, leading to formation of stable nanodomains enriched either lipid or polymer. This stability allowed using vesicle-forming copolymer with a membrane thickness close bilayer...
Phage-based approaches have gained increasing interest as sustainable alternative strategies to antibiotic treatment or prophylactic measures against disease outbreaks in aquaculture. The potential of three methods (oral, bath, and injection) for delivering a two-component phage mixture rainbow trout fry controlling Flavobacterium psychrophilum infections reduce fish mortality was investigated using bacteriophages FpV4 FPSV-D22. For the oral administration experiment, were applied on feed...
nHAP (mainly composed of Ca and P, but also spiked with Sr, V Ce tracers) initially adheres to the surface roots, before penetrating dissolving in plant.
The Bacillus cereus group (Bacillus sensu lato) has a diverse ecology, including various species that are vertebrate or invertebrate pathogens. Few isolates from the B. have however been demonstrated to benefit plant growth. Therefore, it is crucial explore how bacterial development and pathogenesis evolve during colonization. Herein, we investigated thuringiensis (Cry
Double emulsions are very attractive systems for many reasons; the most important of these their capacity to encapsulate hydrophilic and lipophilic molecules simultaneously in a single particle potentiality protect fragile from continuous phase. represent technology that is widely present down micrometer scale; however, double nanoemulsions, with new potential applications as nanomedicines or diagnosis agents, currently significant challenge. In this study, we propose an original two-step...
Efficiency of drug administration is related to the inhibition adverse effects, and can be improved by targeting through lipid nanocarriers encapsulation. Targeting technology generally goes along with nanocarrier functionalization that surface modification and/or ligand grafting. The great advantage nanoemulsions their loading capability possibilities encapsulate several entities in a single droplet, however, decoration droplets strongly anchored reactive functions challenging. This study...
In this paper, superparamagnetic iron oxide nanoparticles (SPIONs, around 6 nm) encapsulated in poly(methyl methacrylate) (PMMA NPs) with controlled sizes ranging from 100 to 200 nm have been successfully produced. The hybrid polymeric NPs were prepared following two different methods: (1) nanoprecipitation and (2) nanoemulsification-evaporation. These methods implemented microprocesses based on the use of an impact jet micromixer elongational-flow microemulsifier. SPIONs-loaded PMMA...
Viral Nervous Necrosis (VNN) causes high mortality and reduced growth in farmed European sea bass (Dicentrarchus labrax) the Mediterranean. In current studies, we tested a novel Pichia-produced virus-like particle (VLP) vaccine against VNN bass, caused by betanodavirus “Red-Spotted Grouper Virus” (RGNNV). were immunized with VLP-based formulated different concentrations of antigen or without adjuvant. Antibody response was evaluated ELISA serum neutralization. The efficacy these VLP-vaccine...
A three‐step microfluidic process is proposed for the production of composite plain and Janus polymeric microparticles doped with polymer nanoparticles. These monodispersed are prepared by means capillaries‐based droplet generators from a dispersed phase obtained after thermally induced or UV‐initiated miniemulsion polymerization size‐controlled oil‐in‐water monomer‐based nanoemulsions produced in novel elongational‐flow microemulsifier. Nanodroplets sizes conveniently varied tuning...
Health concerns associated with the advent of nanotechnologies have risen sharply when it was found that particles nanoscopic dimensions reach cell lumina. Plasma and organelle lipid membranes, which are exposed to both incoming engulfed nanoparticles, primary targets possible disruptions. However, reported adhesion, invagination embedment nanoparticles (NPs) do not compromise membrane integrity, precluding direct bilayer damage as a mechanism for toxicity. Here is shown can be torn by small...
Abstract Bacillus cereus group ( sensu lato ) has a diverse ecology, including various species that are vertebrate or invertebrate pathogens. Few isolates from the B. have however been demonstrated to benefit plant growth. Therefore, it is crucial explore how bacterial development and toxicity evolves during colonization. Herein, we investigated thuringiensis (Cry-) adaptation colonization of Arabidopsis thaliana roots, monitored changes in cellular differentiation experimentally evolved...
