Optically driven micropump produced by three-dimensional two-photon microfabrication

Three-Dimensional Microfabrication by Two-Photon Polymerization

Optically driven Archimedes micro-screws for micropump application.

Archimedes micro-screws have been fabricated by three-dimensional two-photon polymerization using a Nd:YAG Q-switched microchip laser at 532nm. Due to their small sizes they can be easily manipulated, and made to rotate using low power optical tweezers. Rotation rates up to 40 Hz are obtained with a laser power of 200 mW, i.e. 0.2 Hz/mW. A photo-driven micropump action in a microfluidic channel...

Three-dimensional cardiac architecture determined by two-photon microtomy.

Cardiac architecture is inherently three-dimensional, yet most characterizations rely on two-dimensional histological slices or dissociated cells, which remove the native geometry of the heart. We previously developed a method for labeling intact heart sections without dissociation and imaging large volumes while preserving their three-dimensional structure. We further refine this method to per...

Assembly and Molding Processes for Three-dimensional Microfabrication Assembly and Molding Processes for Three-dimensional Microfabrication Assembly and Molding Processes for Three-dimensional Microfabrication

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...
