Metal Nanobumps For Better Artificial Body Parts

Posted by simoniker on from the bumping-this-up dept.

Roland Piquepaille writes "Everybody seems concerned these days by the risks associated with the use of nanotechnologies. So I'm pleased to report that Purdue engineers have proven that metal nano-bumps could improve artificial body parts, such as hips or knees. They based their theory on a simple fact. Surface bumps on conventional alloys used in prostheses are in the micron range, while they are ten times smaller in natural bones, around 100 nanometers. They thought a reduction of the size of these bumps in the prostheses would also reduce the risk of rejection by the body. They limited their experiments to petri dishes, but showed that adherence of new body cells to their new metal alloys was dramatically better than with existing alloys. Ssveral years will pass before improved artificial hips come to market. But the needs are growing. This overview contains more details and references."

    ...but just wait 'til those nonbumps take over the world and kill everyone! Hell, this is probably all an orchestrated ruse by the evil nanotechnology just to get inside the human body. Once they're their, they'll turn us in to their slaves to accomplish their fiendish macroscopic deeds!

    I know you may think I'm crazy, but that's just because I'm wearing a tinfoil hat to keep the nanotechnology's mind control rays out, you're not, and they're already controlling you and are making you think I'm nuts. For proof, just look at those RFID tags: they're actually miniature distributed networks of mind-control processors, just look at this web site for evem more proof.

    I gotta go; I think their agents are on to my location. But you can be sure you'll never see me with a nanotechnology hip. If I ever need a hip, believe me, I'm makin' out of the only technology I trust: tinfoil.

    Nanobumps? I want larger bumps thanks, about DD... and not metal, silicone thanks.

    Imagine a beowulf cluster of nano-bumps!!
