宏观到亚微米尺度的图案和物体是通过使用水凝胶的体积收缩特性对原始图案进行连续小型化而产生的。印模上的图案被转移到水凝胶块上，然后干燥以缩小其尺寸。收缩的图案随后被转移到聚合物印模上，该印模可以用作下一个循环的母版。该图显示了CD（左）和DVD（右）的图案缩小。
Macroscopic to sub-micrometer-scale patterns and objects are generated by successive miniaturization of an original pattern using the volume-shrinking characteristics of hydrogels. A pattern from a stamp is transferred onto a hvdrogel block, which is then dried to shrink its size. The shrunk pattern is subsequently transferred to a polymer stamp, which can be used as master for the next cycle. The figure shows the shrinking of the patterns of a CD (left) and a DVD (right).
