Non-fouling surfaces for reflective spheres
First Claim
1. A reflective substrate comprising a reflective sphere which is configured to be placed on a surgical instrument for use in surgical robotic and navigation systems, the reflective sphere comprising a, liquidphobic structure comprising an organic coating on a sub-micron structured surface of the sphere, wherein the sub-micron textured surface comprises fumed silica nanoparticles adhered to the sphere, and wherein the sphere substantially maintains its reflective properties after the sphere is contacted with a liquid.
