发明名称 | Surface-independent, surface-modifying, multifunctional coatings and applications thereof | ||
摘要 | The present invention provides a surface-independent surface-modifying multifunctional biocoating and methods of application thereof. The method comprises contacting at least a portion of a substrate with an alkaline solution comprising a surface-modifying agent (SMA) such as dopamine so as to modify the substrate surface to include at least one reactive moiety. In another version of the invention, a secondary reactive moiety is applied to the SMA-treated substrate to yield a surface-modified substrate having a specific functionality. | ||

主权项 | 1. A method of modifying a substrate surface to provide a desired functionality, the method comprising: a) contacting at least a portion of the substrate surface with an alkaline, aqueous solution under oxidative conditions, the solution comprising a surface-modifying agent according to Formula I: wherein each of R1, R2, R3, R4 and R5 is independently selected from the group consisting of a thiol, a primary amine, a secondary amine, a nitrile, an aldehyde, an imidazole, an azide, a halide, a hydrogen, a hydroxyl, a carboxylic acid, and an aldehyde, provided at least one of R1, R2, R3, R4 and R5 is not a hydrogen atom; wherein x ranges from 0 to 10 and wherein y ranges from 0 to 10, provided that x or y is at least 1; and wherein the substrate surface is modified; and b) contacting the surface-modified substrate with a reactive moiety comprising a metal, wherein the reactive moiety reacts with and is bound to the modified surface. | ||
