Molding of three-dimensional microstructures of gels.
This Communication describes the use of patterned elastomeric stamps to mold, release, and stack hydrogels into three-dimensional microstructures. Molding of gels against stamps derivatized by a hexa(ethylene glycol)-terminated self-assembled monolayer or by an adsorbed monolayer of bovine serum albumin allowed the application of several soft lithographic techniques (replica molding, microtrans...
متن کاملThree Dimensional Analysis of Microstructures
When using traditional metallographic techniques, materials scientists often make assumptions about the shape, distribution and connectivity of three-dimensional features that lie buried within the material. Recent work has shown that these assumptions can be incorrect. An approach to threedimensional analysis of microstructures is demonstrated here in three different alloy steels. Proeutectoid...
متن کاملSelf-folding of three-dimensional hydrogel microstructures.
This letter describes the fabrication of three-dimensional particulate-like hydrogel microstructures using a combination of soft lithography and volume expansion induced self-folding. Bilayer structures are produced by solvent casting and photocuring of liquid resins. They curl into three-dimensional (3D) structures upon contacting with water due to differential swelling of the two layers. The ...

Lithographic semiconductor microfabrication has been employed with great success for the manufacture of mechanical structures, achieving microscopic dimensions and great complexity at low cost. However, due to the inherently planar nature of the lithographic process, this technology is limited in its capability to produce three-dimensional structures. In this work, three strategies are presente...
متن کاملMechanics and Microstructures of Concentrated Particle Gels
It is often assumed that the viscoelastic properties of dense colloids are determined by the colloid volume fraction, the interaction potential, as well as the particle size distribution and shape. The dependence of the viscoelastic behavior of particle suspensions and gels on these parameters has been widely studied, and is well understood in many cases. In contrast, our knowledge on the influ...
