back to article Boffins build blood-swimming medical microbot

A research team has developed a swimming microrobot designed to navigate through your bloodstream – all with your best interests at heart. Or at lung. Or at the far-flung islets of Langerhans. This diagnostic and therapeutic innovation was announced at this week's International Solid-State Circuits Conference (ISSCC) by Stanford …

Calling Dr. Poon...

Dr. Poon to O.R., We have a little problem here.

ahh but seriously, amazing stuff here. What wonderful times we live in. I for one can't wait until they figure out how to make grey goo. Keep up the good work!

Heh, what?

The Poon Research Group?? Are you serious? Totally not the research I a group named that would be undertaking...

And Dr. Poon?? OMFG. Yea, this has to be April 1st come early.

re. the simulation

If it did actually tilt when turning, as illustrated, then it would drive into the lower wall of the blood vessel. 'Experience' of fixed wing aircraft, or maybe motorbikes, does not translate into other moving devices.

Re: re. the simulation

It also seems to me to be too huge for all but the biggest arteries

Yes, and can't keep up with the speed of the blood-flow either

So 26 years from proposal to build.

Mine will be the one with the rather battered copy of KE Drexlers Engines of Creation in the pocket.

However as Drexler proposed a more "biological" model of nanotechnology (build up by atoms rather than start with a wafer and strip chunks off) he expected them to be mfg by the *billions*.

But it's a start.

To be fair until the noggins come up with a more effecient way of building at the atomic level than with electron microscope then true nanotechnology remains pretty far away mores the pity

Not really.

On the whole the MEMS people have shown more initiative they're more used to *making* stuff that moves.

Biologists and virologists are used to *studying* things that move..

Chemists are used to studying things that move when they are warm.

The 3 other groups *have* made "devices" that are on a similar (or in fact substantially smaller) but typically by the mole (IE 6x10^23) of something.

Wait for it:

I'll continue to consume my chips the traditional way, with a Pint of best.

swimming speed

doesnt blood flow a bit faster than that?

Hardly 'nano' tech

more than 2mm x 2mm is hardly 'nano' technology, and is gonna be severely limited where it can go in a body. I'll pass, thanks.

Re: Hardly 'nano' tech

That's sort of the point. While making big things one atom (or molecule) at a time is tought making *lots* of small (or ideally in this case *really* ) small things is quite easy *once* you've worked out the design.

You're quite right it's *very* much a proof of concept rather than a prototype. While I'm not sure there are *no* blood vessels big enough to take this thing It's likely to be a pretty short list.

"Ada Poon"

I wonder if that phrase was ever uttered by Charles Babbage.

I'll just get my coat and be off to burn in hell for all eternity now.

WTF?

And how does it come out?

Also, this device is too big to travel in many of our arteries and veins. I agree with some other fellows here: I would never let them put this inside me with this size. And I doubt this video properly illustrates how blood really flows inside your body. Looks like it is flying, not swimming against the current.

And don't get me started on the shape....

Rounded edges?

"Odds are that a blood-bound bot will have rounded edges"

Not if they can afford the Apple licence fee it won't.

I'll wait for the one with the cupholder and in-flight entertainment system.

Fry me to the moon

1.86 GHz is somewhat below the 2.45 GHz used in most microwave ovens. Which penetrates organic material just fine, if my morning cholesterol sandwich is anything to go by.

Wavelength has little to do with it. 1.86 GHz waves are in the 15 cm range, way bigger than the 'bot. Ideal aerial length is something you care about when signals are faint - doesn't seem to apply here.

Oh dear

It's hard enough dealing with machines when the rise around us, how are we supposed to handle the ones rising from inside? This ain't going to be pretty.

Hmmm...solid stuff in my bloodstream...

Don't they call them ``clots'', and they give you heart attacks and strokes? I'll let someone else do the beta testing on this one.

Re: Hmmm...solid stuff in my bloodstream...

It won't be a human, that's for 'bloody' certain.

I first thought "pig", but then - elephant is more likely.

"African or Indian?" "Er..I don't know! - .....WAAAAH!"
