Abstract

Seamlessly bridging the hard and the soft, a strategy to fabricate hierarchically porous NiTi/hydrogels nanocomposites is reported. The nanocomposite surface can hold high-content water while keeping its hierarchical nanoscale topography, thus showing exceptional antibiofouling performance. This strategy will lead to antibiofouling alloy (e.g., NiTi)/hydrogel nanocomposites for improved stents and other blood-contacting implants and medical devices.
