Slashdot Mirror
Part-Human, Part-Machine Transistor Devised
asukasoryu writes "Man and machine can now be linked more intimately than ever, according to a new article in the journal ACS Nano Letters. Scientists have embedded a nano-sized transistor inside a cell-like membrane and powered it using the cell's own fuel. To create the implanted circuit, the UC scientists combined a carbon nanotube transistor, lipid bilayer coating, ion pump, and ATP. The ion pump changes the electrical charge inside the cell, which then changes the electrical charge going through the transistor, which the scientists could measure and monitor."
Everyone add the tag, Cylons to this one. :-D
But this is slashdot. A slashdoter who didn't build his own computer is like a Jedi who didn't build his own lightsaber!

I can't help but think of the borg here but I will give them the fact that it is rather ingenues. Hopefully they can generate enough power to do something useful without starving the cell in the future.

So they put a transister inside a cell membrane. How exactly does that make it part human? Every living creature has cells that have phospholipid bilayers.

So will this be the next weight loss method? If I am powering electronics it must come from burning calories correct?
Future devices could work just the opposite, where an outside electrical current could power the pump and alter how quickly ions are pumped into or out of a cell.
That has potentially far reaching effects assuming they can eventually find a way to install these things throughout the body (or even better just on targeted cells). You could install one of these devices on each cancer cell, for example, and power a pump that forced chemo drugs into the cells. That means that cancer cells would receive a much higher dose than non-cancer cells meaning less side effects and/or more effective treatments. Of course, there's a million problems to be solved before such a treatment could become reality, but the possibilities are endless.
Er, well this is Slashdot... but still: I'd rather not, thank-you very much.
"Man and machine can now be linked more intimately than ever" Interesting choice of words, have they never seen the picture that floated around the internet of the man in lingerie, um, "loving" his car's exhaust pipe?
And give up the one chance in you live to become a robotic overlord? WIRE ME! WIRE ME!
I wonder what kinds of numbers something like this could push. Tolerances? Forward / Reverse Bias, Beta values, Depletion region sizes, Breakdown voltages etc...Does anybody have a white-paper link or know if the data is published anywhere public? I am just curious as to how they go about verifying this constructs functionality as a transistor, be it giant simulators, or actual experimental observations.
In the future we will have multimeters / scopes that probe the body's..erm..wait...nvm.

Overlord1: These brutish simple beings have finally yielded some light at the end of the tunnel.
Overlord2: Yes, but it will still be a few centuries to perfect, sell, and drive adoption before we can flip the switch and merge them into Overmind.

Imagine having a wrist calculator that was more reliable than a solar calculator, but you have to eat a bit more.
Let's reverse the flow. Imagine going outside into the sun, and not needing to eat for a day.
Of course, this turns the the whole weight-loss idea on its head. Sunbathing is the new binging: go to the beach paper-thin in your new bikini, and never leave because you've become too morbidly obese to move. Oops.
On the plus side, it could be sold as a cure for world hunger. Bonus points for being green if it makes people sterile in the process (your kids are your biggest carbon footprint, so just say yes to contraception).

According to the actual article, there was no cell involved, only proteins resembling a cell wall. Nor was anything human mentioned.
In short, the article describes how they rapped a protein layer around the nano-transistor and it worked. Then it speculated on what it might be able to do in the future.
While powering a single transistor from the cell is interesting, a single transistor can only be on or off. Since, based on the data supplied in the article, there isn't a mechanism to trigger the on/off state, then it seems to be limited use.
Of more interest is the mention of the research done at the Hebrew University where they accomplished the same thing but by using enzymes that the cell ignored. The reason this is more interesting is that enzymes may be able to be tailored to work with specific cell functions, versus just being powered by the the cell.
Well, certainly looks like the UC scientists aren't the only ones unable to comprehend basic social conventions.
Only a matter of time before we all have our own pc cpu installed inside ourselves and can interface and do a lot of work with our computers and the internet....need to check something up on google, use you interfaced keyboard that sends signals to your cpu, that is powered by your own thermal energy, then use your pc to hook up with the internet using a 3g chip implanted at the base of your neck, this will allow you to look up on google for all the p0rn you might need, and then send the signal back to your optical implant that allows you to visually see your pc screen inside your eyeball.....god i can't wait to see what p0rn will look like when that happens...will they still wear garder belts? what about stilletos?
Yes, the one that didn't FUCKING SUCK BALLS like you do.

The paper appeared in the journal Nano Letters, not to be confused with ACS Nano (although both journals belong to the American Chemical Society). Link: http://pubs.acs.org/doi/abs/10.1021/nl100499x
