Part-Human, Part-Machine Transistor Devised 77

Posted by kdawson from the mitochondria-look-up dept.
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."

  • 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.

    • I'm sure the people actually doing this are fully aware of any issues that could possibly be thought of by a random internet user reading a short overview of the project.

      • No, the average /. reader can pick up in 5 minutes problems in projects that are researched for years. Why else do we read the summeries? Wait till people around here will start to RTFA, then you will really see issues popping up!

      It's powered by the cell, and not its own battery?

      More generally, it is not true to say that a lipid bilayer is even 'biological' in any meaningful sense. Ok, so the ion pump that they used is biological, since it was probably extracted from a cell. There have been designed (artificial) ion pumps, however, which could be used instead.

      Perhaps this is too pedantic, but this is really bio-mimetics rather than bio-chemistry... Anyway, where is Dr Baltar and his detector when we need him? Fracking toasters everywhere!

      Obviously to sensationalize the article. How else to get people to read it? If they just said, “Biologically Powered Transistor Devised”, then people would be all ho hum about it. But if you invoke images of Terminator or Cylons, then people notice. As a matter of fact, nowhere in the article do any of the researchers say anything about this being human. They all refer to the cells in very generic terms. It could be any cells.

    • Fat conversion to ATP through aerobic metabolism is generally slower than other forms of metabolism. It requires a steady supply of oxygen too, so your circulatory system will likely be overworked. Also, rapid breakdown of lipids in the body could lead to metabolic acidosis, decreasing the pH in your blood, and possibly leading to renal/kidney failure.

      So, I doubt fat loss via such a method would be very helpful, or safe.

      Uh? What a stupid statement!
      They connected a transistor to *one* cell: you'd need to connect something to *many* cells before there would be any significant weightloss..

  • 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.

      If you can find a way to install things on targeted cells, you can just deliver the actual chemo to the cells without this as intermediary.

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.

    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.
