AI Insight
Researchers have developed a new 4D biofabrication technology inspired by kirigami, the Japanese art of paper cutting and folding. The technology shows potential applications in tissue engineering and wound healing by creating deployable or transformable biological structures. Similar to how kirigami principles have been applied to spacecraft structures and semiconductors, this approach adapts the folding and cutting technique for biological materials.
Why it matters
This advancement could enable the creation of more sophisticated tissue scaffolds and wound dressings that change shape or structure in response to environmental conditions. The technology may improve outcomes in regenerative medicine by allowing biological constructs to better adapt to complex anatomical sites or healing processes.
Understand the Science
If you’ve ever created a snowflake by folding, cutting and unfolding a piece of paper, you’ve practiced the art of kirigami. Like origami, kirigami has inspired innovations far beyond the elementary school classroom, with applications ranging from deployable structures for spacecraft to semiconductors.
