Metal-mesh lithography (MML) is a practical hybrid of microcontact printing and capillary force lithography that can be applied over millimeter-sized areas with a high level of uniformity. MML can be achieved by blotting various inks onto substrates through thin copper grids, relying on preferential wetting and capillary interactions between template and substrate for pattern replication. The resulting mesh patterns, which are inverted relative to those produced by stenciling or serigraphy, can be reproduced with low micrometer resolution. MML can be combined with other surface chemistry and lift-off methods to create functional microarrays for diverse applications, such as periodic islands of gold nanorods and patterned corrals for fibroblast cell cultures.
金属网版印刷术(MML)是微接触印刷术和毛细作用力印刷术的实际混合体,可以在毫米级的大面积上实现高度均匀性。通过将各种油墨通过薄铜网印到基底上,可以实现 MML,这依赖于模板和基底之间的优先润湿和毛细相互作用进行图案复制。得到的网孔图案与模版印刷或丝印产生的图案相反,可以以低至微米的分辨率再现。MML 可以与其他表面化学和剥离方法结合,为各种应用创建功能性微阵列,例如周期性的金纳米棒岛和用于成纤维细胞培养的图案化珊瑚礁。
