Laser-patterned thin films that swell into kirigami-like structures offer new opportunities in hydrogel technology. TSUKUBA, Japan, Apr 12, 2024 - (ACN Newswire) - New options for making finely structured soft, flexible and expandable materials called hydrogels have been developed by researchers at Tokyo University of Agriculture and Technology (TUAT). Their work extends the emerging field of ‘kirigami hydrogels’, in which patterns are cut into a thin film allowing it to later swell into complex hydrogel structures. The research is published in the journal Science and Technology of Advanced Ma...

A new technique allows researchers to map how the cellular 'skeleton' adapts to external stress. TSUKUBA, Japan, Nov 21, 2023 - (ACN Newswire) - By giving living cells a ‘nano-poke’ and monitoring the resulting changes in the intra-cellular environment, researchers have gotten their first glimpse of how whole cells respond to external mechanical pressure. A team lead by scientists from the National Institute for Materials Science in Tsukuba, Japan, used a technique called atomic force microscopy to apply force across the surface of various cells. The method uses nanoscale probes, with tips jus...
