MIT developed a new way of making tough — but soft and wet — biocompatible materials, called “hydrogels,” into complex and intricately patterned shapes. The new biocompatible tough hydrogel can be printed into diverse 3-D structures such as a hollow cube, hemisphere, pyramid, twisted bundle, multilayer mesh, or physiologically relevant shapes, such as a human nose or ear. The process might lead to injectable materials for delivering drugs or cells into the body; scaffolds for regenerating load-bearing tissues; or tough but flexible actuators for future robots. This new process is described in a paper in the journal Advanced Materials.
