Controlled fabrication of hierarchically microstructured surfaces via surface wrinkling combined with template replication

Multiscale engineered hierarchical structures with precisely controlled sizes for bio-inspired cell culture

“…An extensive effort has been made through interdisciplinary research to obtain an in vivo-like artificial ECM [14][15][16]. However, most of the preceding results are partially limited in their similarity to a natural ECM due to technical difficulties in fabricating a multiscale structure.…”

Parallel Nanoimprint Forming of One-Dimensional Chiral Semiconductor for Strain-Engineered Optical Properties

“…The selection of suitable molding substrates with patterned surfaces is crucial for this method [ 59 ]. The commercial compact disk (CD) and digital versatile disk (DVD) encode their information by a spiral track molded onto the top of a polycarbonate layer [ 102 ]. The spiral tracks on blank CDs and DVDs have depths around hundreds of nanometers, and the distance between each neighboring track varies from 850 nm to 2 um [ 102 ].…”

The surface patterns with precise periodicities and low cost of blank CD and DVD make them ideal substrates for the nanoimprinting process.…”

Dynamic Interpenetrating Polymer Network (IPN) Strategy for Multiresponsive Hierarchical Pattern of Reversible Wrinkle

“…Furrows generated on animal skin or plant surfaces accommodate the aging process . A variety of methods, such as mechanical prestretching–compression, − thermal expansion, , solvent swelling, − and capillarity, have been developed for wrinkle fabrication. Furthermore, the dynamic wrinkles with responsive surface topography that can be adjusted by external stimuli, may enable the on-demand regulation of the surface characteristic, and might be essential and intriguing for a variety of applications, including information security, , tunable optical devices, − flexible electronics, − energy storage, , membrane separation, switchable wettability, , and smart adhesion …”
