N2 - This paper describes core-shell hydrogel microsprings that encapsulate various functional materials inside. Core-shell hydrogel microsprings were spontaneously assembled by using a bevel-tip capillary with coaxial-la minar flow: the outer flow is sodium a lginate solution and the inner f low contains functional materials. We found that the microspring formation mainly depends on the rapid anisotropic-gelation of thin outer calcium alginate hydrogel, regardless of the properties of core materials. Using this feature, we successfully demonstrated various types of hydrogel microsprigs encapusulating functional materials. We believe that our method would be powerful approach to various microscale biochemical applications including soft actuators/sensors and scaffolds for cells.
