An optimal medical scaffold should be biocompatible and biodegradable have adequate mechanical properties architecture porosity, a precise three-dimensional shape, reasonable manufacturing method. Polylactic acid (PLA) is natural thermoplastic aliphatic polyester that can fabricated into nanofiber structures through many techniques, electrospinning one of the most widely used methods. Medical fiber mat scaffolds been associated with inflammation infection and, in some cases, resulted tissue...
More than half of the hospital-associated infections worldwide are related to adhesion bacteria cells biomedical devices and implants. To prevent these infections, it is crucial modify biomaterial surfaces develop antibacterial property. In this study, chitosan (CS) chondroitin sulfate (ChS) were chosen as coating materials on polylactic acid (PLA) surfaces. Plasma-treated PLA coated with CS either direct method or carbodiimide coupling method. As a next step for combined saccharide coating,...
The use of polymers in all aspects daily life is increasing considerably, so there high demand for with specific properties. Polymers antibacterial properties are highly needed the food and medical industries. Low-density polyethylene (LDPE) widely used various industries, especially packaging, because it has suitable mechanical safety Nevertheless, hydrophobicity its surface makes vulnerable to microbial attack culturing. To enhance antimicrobial activity, a progressive modification LDPE...
Many polymer materials have found a wide variety of applications in biomedical industries due to their excellent mechanical properties. However, the infections associated with biofilm formation represent serious problems resulting from initial bacterial attachment on polymeric surface. The development novel slippery liquid-infused porous surfaces (SLIPSs) represents promising method for prevention. These are characterized by specific microstructural roughness able hold lubricants inside....
Polylactic acid (PLA) is one of the most produced polymeric materials, due to its exceptional chemical and mechanical properties. Some them, such as biodegradability biocompatibility, make them attractive for biomedical applications. Conversely, major drawback PLA in field their vulnerability bacterial contamination. This study focuses on immobilization saccharides onto surface by a multistep approach, with aim providing antibacterial features evaluting synergistic effect these saccharides....
ABSTRACT Bacterial contamination is one of the biggest drawbacks implanted biomaterials, which may cause nosocomial infection. Avoiding bacterial adhesion onto biomaterial surface by preparing active antibacterial biomaterials an accurate solution. In this study, three fluoroquinolones: sparfloxacin, enrofloxacin, and lomefloxacin were selected due to their broad bactericidal effect immobilized low‐density polyethylene at two different pH values (pH 3 6), after tailoring plasma treatment...
The development of antibacterial materials has great importance in avoiding bacterial contamination and the risk infection for implantable biomaterials. An thin film coating on surface via chemical bonding is a promising technique to keep native bulk material properties unchanged. However, most polymeric are chemically inert highly hydrophobic, which makes agent challenging Herein, immobilization chlorhexidine, broad-spectrum bactericidal cationic compound, onto polylactic acid was performed...
Ion implantation of metal ions, followed by annealing, can be used for the formation buried layers nanoparticles in glasses. Thus, photonic structures with nonlinear optical properties formed. In this study, three samples silica glasses were implanted Cu+, Ag+, or Au+ ions under same conditions (energy 330 keV and fluence 1 × 1016 ions/cm2), compared to identical glass that subsequently coimplanted oxygen at depth. All annealed 600 °C h, which leads nanoparticles. The depth profiles Cu, Ag,...
This paper reposts on nanofibers of polymers doped with ferrous sulphate (FeSO4) possibly in combination quaternary ammonium salt (QAS) prepared by electrospinning.Three types (polyvinylidene fluoride/PVDF, polylactic acid/PLA and polyurethane/PU) good electrospinning processability mechanical properties were chosen.The nanofibrous membranes characterised terms morphology the fibres assessed SEM, pore sizes determined porometry.The leaching test showed a firm anchoring additive nanofiber...
