While the material itself was discovered back in the 1990s by some Harvard guys, scientists only recently stumbled across its antibacterial properties after studying the wings of cicadas and dragonflies. They discovered that nanostructures shaped like little pillars on the wings effectively shreds and kills any bacteria that tried to settle there. With spikes that are just 500 nanometers high, black silicon pictured above has the same property. Bacteria literally can ;t land on the surface without being destroyed by the spikes. Now for the potential downside. While useful for camer

The scientists who discovered black silicon antibacterial properties are optimistic that they can produce synthetic nano-materials that will have the same effect. Now if they could only figure out an easy solution to our antibiotic problem. [AFP] Image via Wikipedia antibioticsBacteriaScience
