    • The invention relates to an activated metallic, semiconductor, polymer, composite and/or ceramic substrate, the substrate being bound through a mixed or graded interface to a hydrophilic polymer surface that is activated to enable direct covalent binding to a functional biological molecule, the polymer surface comprising a sub-surface that includes a plurality of cross-linked regions, as well as to such activated substrates that have been functionalised with a biological molecule and to devices comprising such functionalised substrates. Such substrates can be produced by a method comprising steps of: a. exposing a surface of the substrate to any or more of (i) to (iii): (i) plasma ion implantation with carbon containing species; (ii) co-deposition under conditions in which substrate material is deposited with carbon containing species while gradually reducing substrate material proportion and increasing carbon containing species proportion; (iii) deposition of a plasma polymer surface layer with energetic ion bombardment; incubating the surface treated according to step (a) with a desired biological molecule.
    • 本发明涉及活化的金属,半导体,聚合物,复合材料和/或陶瓷基材,所述基材通过混合或分级界面结合到亲水性聚合物表面,所述界面被活化以实现与功能性生物分子的直接共价结合,所述聚合物 表面,其包括包含多个交联区域的子表面,以及已经用生物分子官能化的这种活化的底物和包含这种官能化底物的装置。 这样的基材可以通过包括以下步骤的方法制备:a。 (i)至(iii)中的任何一种或多种:(i)用含碳物质进行等离子体离子注入; (ii)在使含有碳的物质沉积衬底材料的条件下共沉积,同时逐渐降低衬底材料比例并增加含碳物质比例; (iii)用能量离子轰击沉积等离子体聚合物表面层; 将根据步骤(a)处理的表面与所需的生物分子一起孵育。
