The interaction between metal nanoparticles and bacteria belongs to the central issues in a dynamically growing bionanotechnological research. Herein, we investigated adhesion efficiency of gold (30 nm) for various bacterial strains, both Gram-positive (Bacillus subtilis, Staphylococcus carnosus) Gram-negative (Neisseria subflava, Stenotrophomonas maltophilia). thorough microscopic (SEM/TEM) observations revealed that do not penetrate into cells but adhere walls. Large differences adhered...
In this work we have investigated the effect of oxygen plasma treatment graphenic surfaces and introduction functional groups on changes in function, wettability, surface free energy bacterial adhesion. The parameters were adjusted (generator power: <60 W, exposure time: <20 min) to limit modifications without changing bulk structure. parent modified thoroughly characterized by μRaman spectroscopy, thermogravimetry, scanning electron microscopy, contact angle, X-ray photoelectron function...
Abstract Additives in vaping products, such as flavors, preservatives, or thickening agents, are commonly used to enhance user experience. Among these, Vitamin E acetate (VEA) was initially thought be harmless but has been implicated the primary cause of e-cigarette product use-associated lung injury, a serious disease. In our study, VEA serves proxy for other additives. To explore its harmful effects, we developed an exposure system subject pulmonary surfactant (PSurf) model VEA-rich vapor....
The interaction between bacteria and nanoparticles is currently a central topic in bionanotechnology.
A graphene oxide nano film, known for its insulating properties, when deposited on conducting substrates, redirects the flow of electrons, leading to death bacteria.
This study investigates the interaction of two approved and one newly developed latanoprost formulation with in vitro silico models tear film lipid layer (TFLL). Latanoprost, a prostaglandin analogue used for intraocular elevated pressure treatment, is topically delivered by nanocarriers within aqueous solutions or emulsions. The focuses on impact these carriers drug interactions their effect TFLL. Three different types carriers, micellar, nanoemulsion, polymer-based, were compared, each...
This article demonstrates preparation of metal functionalized zeolite catalysts via a new homogeneous solution pathway enabled by the recently reported exfoliation MWW into unilamellar nanosheets. The is carried out mixing solutions exfoliated monolayers and Pt nanoparticles with initial size ca 3 nm isolation such hybrid freeze-drying. Optionally, layer were purified dialysis prior to solution, which turned be beneficial for quality textural characteristics. However, catalytic performance...
