Engineering a Biocompatible Scaffold with Either Micrometre or Nanometre Scale Surface Topography for Promoting Protein Adsorption and Cellular Response

“…A similar approach uses self-folding, a self-assembly process in which planar structures fold up from the 2D substrate when exposed to specific activation stimuli [156]. For example, laser origami uses a laser direct-write technique to produce feature through laser fabrication of the pattern in the substrate, then deposit the active elements on the pattern via laser transfer or cutting and finally the substrate is heated using the laser which results in the cut patterns folding up out of the substrate [156]. The other recent technique is Multiphoton lithography (MPL) which can be used to fabricate 3D tissue scaffold structures.…”

Microfabricating 3D structures by laser origami

“…This process can be applied to the formation of structures for use in actuating elements triggered by a laser pulse and also to hoist out-of-plane components or devices attached to the copper foil. 3 In another implementation, we have shown actuation from volumetric contraction during solvent evaporation of metallic nanoinks. These inks consist of suspended metallic nanoparticles in a highly viscous, organic solution.…”

Self‐Organized Origami Structures via Ion‐Induced Plastic Strain

“…New technologies could develop if such processes could be reproduced and controlled artificially, to create three‐dimensional (3D) objects endowed with functionality inspired from the biological world. In material science, the origin of stresses (grain boundaries, impurities, lattice mismatch, thermal expansion, intersubstrate diffusion) and effects such as film curvature resulting from grain coalescence, heat absorption, and electromagnetic radiation have attracted a constant interest 6–11. Combining strain engineering with thin film lithography has allowed the assembly of simple 3D structures, such as pipelines, helices, and tubes,12–17 with potential applications ranging from biology to optics18–20 However, in order to create structures that would function as complex nanodevices, one needs a technology that enables us to control the assembly process at a much better precision than the scale of the designed structure.…”
