By exploiting surface acoustic waves and a coupling layer technique, cells are patterned within a photosensitive hydrogel fiber to mimic physiological cell arrangement in tissues. The aligned cell–polymer matrix is polymerized with short exposure to UV light and the fiber is extracted. These patterned cell fibers are manipulated into simple and complex architectures, demonstrating feasibility for...
Four surface‐acoustic‐wave (SAW) devices that create organized cellular fibers with differing cell types (purple, red, green, orange) are shown. As T. J. Huang and co‐workers describe on page 8632, the SAWs pattern cells within a polymer solution, which is polymerized and extracted to make complex tissue structures. The organization of cells within such fibers mimics the cellular organization found...
