Houseplant Inspires Textured Surfaces to Mitigate Copper IUD Corrosion

In Biointerphases, researchers take inspiration from a common houseplant to develop a better, safer copper IUD. The researchers noticed that pothos leaves are hydrophobic -- a distinctive microstructure on the leaf's surface causes water droplets to ball up and slide off. The team realized that mimicking this pattern on the surface of a copper IUD might repel uterine fluid. Less contact between the surface and fluid would decrease corrosion, releasing fewer copper ions and mitigating side effects.
