    I was wondering what would be the energy source for nanomachines,especially those for the human body?
    today`s batteries are not very efficient and I dont see how a nanomachine would recharge.

    I wouldn't be surprised if they figure out a way to use the individual's own plasma to recharge the nanomachines. Plasma is full of electrolytes that are necessary for many chemical reactions. If the nanomachines had chloride in them, they could draw sodium into them to make a charged ion, which would provide a small amount of energy. The plasma contains not only sodium, but also potassium, calcium, copper, selenium--all of which can be used in such chemical reactions.

    But then, if the nanomachine were just intended for a quick repair of, say a vein in the heart or something, it may not need to have a lasting charge and could easily be charged outside the body for a specific amount of time, manipulated into position for repairs, and then retrieved upon completion.

    How does a cell power itself?

    A misconception about nanotechnology is that there will be little micromachines inside of us. The reality is that most things that small are more effective when made of organic materials (like cells). who woulda guessed that we were already so 'perfect'. Anyways, when you get to that scale, things such as ATP and atomic energies (not sure if that is the right term) are much better than batteries.

    For example in the muscles. Energy (ATP) is used to relax the myosin (in a sense). The acctual action of flexing the muscle comes from the structure and power of molecular bonds. It is very fascinating.

    Back to that misonception. What I mean is that instead of little machines inside of us there will be synthetic (or man made) cells inside of us. These cells (like our cells) will use natural energy sources (like we do). Hmmm... makes you wonder... what is the point?

    I seem to remember something about small, non-harmful lazers being used to push along a "cart"...

    I don't know how accurate that is, or if it was just an idea at the time.

    :? talking about borg technology or something??

    their nanobots gain energy from batteries inside the body. but they'll form energy from corrosion when they get out of the body.

    best idea to power a device like that create waves that activate/rotate certain particles. And the nanobots would contain those particles. Like polarised uranium or something like that.
    Growing up, i marveled at star-trek's science, and ignored the perfect society. Now, i try to ignore their science, and marvel at the society.

    Imagine, being able to create matter out of thin air, and not coming up with using drones for boarding hostile ships. Or using drones to defend your own ship. Heck, using drones to block energy attacks, counterattack or for surveillance. Unless, of course, they are nano-machines in your blood, which is a billion times more complex..

    Hi everyone this is my first time on this forum,
    Agreeing partially with DaBOB, nanomachines (bots, whatever) should not be enterpreted as macromachines (your computer, telephone etc) which are driven by electrical energie.

    ATP (adenosine triphosphate) or other family members (such as GTP) for example can be an energie source making these machines active.

    What I mean is that instead of little machines inside of us there will be synthetic (or man made) cells inside of us.
    I don't think one should consider the nano machines as cells, since cells are extremely complicated units. Instead you should see them as molecules needing chemical energie to adapt a conformational change (to do their work).

    actually it may have fatal consequences when fails, but it is a promising novel approach that needs many years to be mature. I am optimistic.

    SinMan:

    Have they figured out how to harness ATP hydrolyis to power nanomachines? Do you know the mechanism?

    I'm impressed if they have!

    Hi leukocyte

    Well, the biochemistry is full of nano machines that are powered by ATP hydrolysis e.g. ATPase, DNA-polymerase and more.

    After your question I looked back in a science magazine dating from 3 years ago, I think, and found also an example of a nano rotor that can be spinned by applying light to it.

    Sorry, I was talking about man-made nanomachines using ATP hydrolysis for fuel, not enzymes.

    Miscommunication!

    Right, nanomachines can be enzymes, why not. Man-made is, in my point of view, not so well chosen. Why should we build a machine starting from a single atom, if there is a plenty of machines already out there. Modifyning such enzymes can be good I should suggest.
    Using nanomachines as tiny units to send into a body for fixing something is still far-fetched.

    Interesting idea about the Nanobots, i read something on the net about, (in the future) Nanobots being put into the bloodstream to directly attack and kill cancer cells.

    See I think you understand my point but don't realize it (or maybe you do).

    I was saying instead of nanomachines we would have synthetic cells. What I am getting at is that because cells are so much more complicated and work so well I see no reason for creating lesser 'machines' for our bodies. Also, I was getting at the idea that they would not act like machines, unless they were larger. Maybe nano or micro parts creating larger machines. They still may be small enough to fit certain places though. But, it is more like molecules.

    I have been in a nano-tech class. Got to wear the buny suit and all that. It was alot different than I had imagined. Instead of working with parts (like on a car or something) you are working with chemicals. Trying to manipulate them with machines that use gasses and plasmas. It is very dirty work in my opinion. Also, you cannot see what you are working on. You have to use special equipment that helps create an idea of the structure but, at that level you can't just use a microscope. Even the electron microscope wasn't a very clean picture. It is cool stuff though.

    So are nanomachines just controllable living / not living things then??

    All they say about machines are the thing that they are controlled. In some ways Pennecilline are nanomachines then. Or not?

    the most advanced robot in the world is honda`s asimo.The most impressive thing it can do is climbing stairs.
    So there is no way we will see nanomachines for at least the next 100 years.(except those very basic ones.)

    Hi Zwolver,
    penicilline is a chemical compound that is absolutely not a nano machine. It helps killing deviding bacteria by disrupting their peptydoclycane (some kind of cell wall) formation. It acts by binding to a certain enzyme that forms peptidoglycane.

    please read this:

    I know, still it fits the description of a nanomachine as an enzyme.

    Ok I have already tried to explain this. Nanomachines are in the very near future, in fact a living cell could be considered a nonomachine, it could possible even be considered man made in a sense. But, that is besides the point. The point is a nano metre is so small that a nanomachine is not like a robot. It is much more messy and (obviously) small. Yes many modern drugs could in fact be considered nanomachines but, nanomachine technology still has many advances to be made. By this I mean these machines may be programable or have small memory banks or what not. I wouldn't get to mechanical when thinking about them though. Think Chemistry not robotics.

    Hi BOB,
    with all my respect, what are your references? How do you get this to work: "a living cell could be considered a nonomachine"? OR "Yes many modern drugs could in fact be considered nanomachines". AND "I wouldn't get to mechanical when thinking about them ". They are pretty mechanical in some way.

    that's what i meant, not that pennicilline are enzymes.. but enzymes have a specific function and so do pennicilline.

    I will try to explain.

    When you are at the "nano level" things are just to small. You can't have a nanomachine that has gears and bearings and other moving parts and still be that small. The parts may be small but the whole machine will be more like a micromachine. A cell could be looked at like this.

    For example: this nano arm (fine motion controller) has less that 3,000 atoms.

    Anyways, what I am getting at is that a machine has to be very small in order to be considered nano. The smaller it gets the less complicated it gets. Untill you are litterally down to single molecules (or small clusters of atoms). Red stained glass windows have gold 'nanoparticles' in them. When gold particles are that small they reflect red light. So in a sense the gold is a nanomachine turning sunlight (or any light) into red light and yet it is a single element.

    Does that help?
