Targeted surgery requires spatial and temporal selectivity, which is an elusive goal; the realization of this goal may be aided by materials that undergo conformational changes in response to remote ...

Hydrogels have demonstrated promise for effectively treating skin wounds. However, currently available hydrogels adhere to the skin and swell when absorbing fluid discharge, causing the wound site to ...

Empa researchers are working together with clinical partners on a model of human skin. The model will allow scientists to simulate skin diseases and thus better understand them. The skin is the ...
