Writing in the granular gel medium
Writing in the granular gel medium. Tapomoy Bhattacharjee et al (2015), Science Advances Gels made from soft microscale particles smoothly transition between the fluid and solid states, making them an ideal medium in which to create macroscopic structures with microscopic precision. While tracing out spatial paths with an injection tip, the granular gel fluidizes at the point of injection and then rapidly solidifies, trapping injected material in place. This physica
