Abstract Scope Surface micropatterning can add valuable functionalities such as new mechanical and optical properties through metamaterial surface patternings, or tailored wetting properties or chemical reactivities through microtextured or chemically patterned surfaces. But traditional microlithographic approaches are limited to patterning only hard materials with flat, or gently curving, surfaces. Recently, a new transfer microprinting approach was introduced that extends such patterning to arbitrary materials and 3-dimensional structures that may include high curvatures and sharp edges Science <B>378</B>, 894 (2022)]. This talk introduces this new transfer microprinting approach, which requires little more than regular table sugar, an inexpensive material that spontaneously conforms to arbitrary surface geometries when heated and reflowed, enabling physically and chemically gentle micropatterning of multiple materials including metals, semiconductors, glasses and multiple soft polymeric materials.
