    • The present invention provides a series of methods, compositions, and articles for patterning a surface with multiple, aligned layers of molecules, by exposing the molecules to electromagnetic radiation. In certain embodiments, a single photomask acts as an area-selective filter for light at multiple wavelengths. A single set of exposures of multiple wavelengths through this photomask may make it possible to fabricate a pattern comprising discontinuous multiple regions, where the regions differ from each other in at least one chemical and/or physical property, without acts of alignment between the exposures. In certain embodiments, the surface includes molecules attached thereto that can be photocleaved upon exposure to a certain wavelength of radiation, thereby altering the chemical composition on at least a portion of the surface. In some embodiments, the molecules attached to the surface may include thiol moieties (e.g., as in alkanethiol), by which the molecule can become attached to the surface. In some embodiments, the molecules may be terminated at the unattached end with photocleavable groups. In other embodiments, a molecule that was photocleaved may be exposed to another molecule that binds to the photocleaved molecule. In certain cases, the molecules may be terminated at the unattached end with hydrophilic groups that may, for example, be resistant to the adsorption of proteins. In other cases, the molecules may be terminated at the unattached end with end groups that are not resistant to the adsorption of proteins. In certain embodiments, the techniques are used to pattern simultaneously two different regions that are resistant to the adsorption of proteins, and a third region that does not resist the adsorption of proteins.
    • 本发明通过将分子暴露于电磁辐射来提供一系列方法,组合物和用于图案化具有多个对准的分子层的表面的制品。 在某些实施例中,单个光掩模用作多个波长的光的区域选择滤光器。 通过该光掩模的多组波长的一组曝光可以使得可以制造包括不连续多个区域的图案,其中区域在至少一种化学和/或物理性质上彼此不同,而不影响曝光之间的对准。 在某些实施方案中,表面包括附着于其上的分子,其可以在暴露于一定波长的辐射时被光刻,从而改变表面的至少一部分上的化学组成。 在一些实施方案中,连接到表面的分子可以包括硫醇部分(例如,如在链烷硫醇中),分子可以通过该分子附着到表面。 在一些实施方案中,分子可以在不附着的端部用可光致发光的基团终止。 在其它实施方案中,被光致剪切的分子可以暴露于结合光刻分子的另一个分子。 在某些情况下,分子可以在亲水基团的末端被终止,所述亲水基团例如可以抵抗蛋白质的吸附。 在其他情况下,分子可以在不附着于不附着蛋白质的端基的端基处终止。 在某些实施方案中,所述技术用于同时模拟对蛋白质的吸附具有抗性的两个不同区域,以及不抵抗蛋白质吸附的第三区域。
