Abstract Formation of unwanted deposits on steels during their interaction with liquids is an inherent problem that often leads to corrosion, biofouling and results in reduction durability function. Here we report a new route form anti-fouling steel surfaces by electrodeposition nanoporous tungsten oxide (TO) films. TO-modified are as mechanically durable bare highly tolerant compressive tensile stresses due chemical bonding the substrate island-like morphology. When inherently...
There is a dire need for infection prevention strategies that do not require the use of antibiotics, which exacerbate rise multi- and pan-drug resistant infectious organisms. An important target in this area bacterial attachment subsequent biofilm formation on medical devices (e.g., catheters). Here we describe nonfouling, lubricant-infused slippery polymers as proof-of-concept materials are based oil-infused polydimethylsiloxane (iPDMS). Planar tubular geometry silicone substrates can be...
Inspired by the long-term effectiveness of living antifouling materials, we have developed a method for self-replenishment synthetic biofouling-release surfaces. These surfaces are created either molding or directly embedding 3D vascular systems into polydimethylsiloxane (PDMS) and filling them with silicone oil to generate nontoxic oil-infused material. When replenished from an outside source, these materials capable self-lubrication continuous renewal interfacial fouling-release layer....
Omniphobic coatings are designed to repel a wide range of liquids without leaving stains on the surface. A practical coating should exhibit stable repellency, show no interference with color or transparency underlying substrate and, ideally, be deposited in simple process arbitrarily shaped surfaces. We use layer‐by‐layer (LbL) deposition negatively charged silica nanoparticles and positively polyelectrolytes create nanoscale surface structures that further surface‐functionalized fluorinated...
The stability and longevity of surface-stabilized lubricant layers is a critical question in their application as low- nonfouling slippery surface treatments both industry medicine. Here, we investigate loss from surfaces under flow water using quantitative analysis visualization, testing the effects underlying type (nanostructured versus flat), well rate physiologically relevant range, type, time. We find losses on order only ng/cm2 closed system, indicating that these interfaces are...
Significance Inspection devices are frequently occluded by highly contaminating fluids that disrupt the visual field and their effective operation. These issues particularly striking in endoscopes, where diagnosis treatment of diseases compromised obscuring operative body fluids. Here we demonstrate application a liquid-infused surface coating strongly repels sticky biological secretions enables an uninterrupted view. Extensive bronchoscopy procedures performed vivo on porcine model shows...
Microbial adhesion to medical devices is common for hospital-acquired infections, particularly urinary catheters. If not properly treated these infections cause complications and exacerbate antimicrobial resistance. Catheter use elicits bladder inflammation, releasing host serum proteins, including fibrinogen (Fg), into the bladder, which deposit on catheter.
The structure and stability of single- double-stranded DNA hybrids immobilized on gold are strongly affected by nucleotide–surface interactions. To systematically analyze the effects these interactions, a set model was prepared in conformations that ranged from end-tethered to directly adsorbed single-stranded (hairpins) characterized surface plasmon resonance (SPR) imaging, X-ray photoelectron spectroscopy (XPS), fluorescence microscopy, near edge absorption fine (NEXAFS) spectroscopy....
The ability to control the properties of bio-inspired liquid-infused surfaces is interest in a wide range applications. Liquid layers created using oil-infused polydimethylsiloxane elastomers offer potentially simple way accomplishing this goal through adjustment parameters such as curing agent ratio and oil viscosity. In work, effect tuning these compositional on infused polymer are investigated, including infusion dynamics, stiffness, longevity face continuous liquid overlayer removal,...
Bacterial interactions with surfaces are at the heart of many infection-related problems in healthcare. In this work, clinically relevant bacteria immobilized liquid (IL) layers on oil-infused polymers investigated. Although reduce bacterial adhesion all cases, complex and layer under orbital flow conditions uncovered. The number adherent Escherichia coli cells over multiple removal cycles increases compared to static growth conditions, likely due a disruption continuity. Surprisingly,...
Filamentous fungi have been considered as candidates to replace petroleum-based adhesives and plastics in novel composite material production, particularly those containing lignocellulosic materials. However, the nature of role surface mycelium adhesion between components is not well-known. The current study investigated functionality for wood bonding by incubating Trametes versicolor on yellow birch veneers compared lap-shear strengths after hot-pressing evaluate if presence can improve...
