23 Jul THREE-DIMENSIONAL SILICON SCAFFOLD FOR TISSUE ENGINEERING
Abstract
Three-dimensional scaffolds to facilitate engineered tissue growth are described herein. An exemplary scaffold comprises a first capillary element, a second capillary element, and a connective element that spans a distance between the first capillary element and the second capillary element, connecting the capillary elements. Tissues can be grown within the scaffold such that the tissues have highly vascularized structures with many capillaries running throughout. The scaffolds can be fabricated by selective electrochemical etching of a semiconductor element. The electrochemical etching can be controlled by way of a laser configured to stimulate multiphoton absorption in the semiconductor.
