Chameleon Color-Shifting Improves Implants
Chameleons change color using specialized nanostructures. Caltech researchers created pacemaker coatings that detect and respond to pH changes in the body. When inflammation rises, these coatings release medication automatically. Tests last year showed a 25% reduction in rejection rates. FDA approval could come by 2027, making implants that adapt to each patient’s unique conditions. These smart surfaces sense their environment and change their properties accordingly, just like a chameleon’s skin.
