摘要： Substrates, optionally coated with an undercoating, having grafted thereto one or more non-fouling materials are described herein. The non-fouling, polymeric material can be grafted to a variety of functionalized substrate materials, particularly polymeric substrates and/or polymeric undercoatings immobilized on a substrate. The compositions described herein are highly resistant protein absorption, particularly in complex media and retain a high degree of non-fouling activity over long periods of time. The compositions described herein may also demonstrate antimicrobial and/or anti-thrombogenic activity. The non-fouling material can be grafted to a functionalized substrate, or optionally from an undercoating on the substrate, preferably without significantly affecting the mechanical and/or physical properties of the substrate material

摘要： Synthetic amino acids containing one or more non-fouling groups or moieties are described herein. In one embodiment, the amino acid has the following chemical formula: where L is a linker group and Z is a non-fouling group including, but not limited to, polyethylene glycol (PEG); oligoethylene glycol (OEG); zwitterionic group, such as phosphorycholine, carboxybetaine, and sulfobetaine; groups that are hydrogen bond acceptors but not hydrogen bond donors. The non-fouling amino acids can be incorporated into a bioactive peptide as single amino acid residues, multiples amino acid residues, or as blocks of amino acids. The non-fouling amino acids, or peptides containing one or more non-fouling amino acids, can be applied to surfaces in order to improve biocompatibility, reduce thrombogenesis, and/or reduce fouling by proteins or bacteria present in solution.

摘要： Compositions containing one or more types of membrane-targeting antimicrobial agents immobilized on a substrate with activity in relevant biological environments, and methods of making and using thereof, are described herein. The antimicrobial agents retain their activity in the presence of blood proteins and/or in vivo due to improved molecular structures which allow for cooperative action of immobilized agents and hydrophilic chemistries which resist non-specific protein adsorption. Suitable molecular structures include branched structures, such as dendrimers and randomly branched polymers. The molecule structures may also include hydrophilic tethers which provide both flexibility and resistance to non-specific protein adsorption. The membrane targeting antimicrobial agent coatings can be applied to a variety of different types of substrates including medical implants such as vascular grafts, orthopedic devices, dialysis access grafts, and catheters; surgical tools, surgical garments; and bandages. The substrates can be composed of metallic materials, ceramics, polymers, fibers, inert materials such as silicon, and combinations thereof. The compositions described herein are substantially non-leaching, resistant to non-specific protein adsorption, and non-hemolytic.
摘要翻译：本文描述了包含固定在具有相关生物环境中的活性的基质上的一种或多种类型的膜靶向抗微生物剂的组合物及其制备和使用方法。抗微生物剂在血液蛋白质存在下和/或体内保留其活性，因为改进的分子结构允许固定化剂和抵抗非特异性蛋白质吸附的亲水化学物质的协同作用。合适的分子结构包括支链结构，例如树枝状聚合物和无规分支的聚合物。分子结构还可以包括提供灵活性和对非特异性蛋白质吸附的抗性的亲水系链。膜靶向抗微生物剂涂层可以应用于各种不同类型的基底，包括医疗植入物，例如血管移植物，矫形装置，透析入口移植物和导管; 手术工具，手术衣服; 和绷带。基板可以由金属材料，陶瓷，聚合物，纤维，惰性材料如硅构成，以及它们的组合。本文所述的组合物基本上是非浸出的，对非特异性蛋白质吸附抗性和非溶血性的。
