It seems like everyone is trying to make nanomachines these days, usually through some expensive procedure like carving them out of an exotic material with a laser. In an effort to produce cheaper machines, researchers at Purdue University have created a magnetic ink that can be printed onto any paper, instantly turning it into the material for small tweezers or even micro-speakers.
The technique utilizes iron oxide nanoparticles suspended in an oily ink. Once the oil prints out on a piece of paper, the paper becomes magnetic. These magnetic paper components could significantly benefit nano-biological work, as the paper is much softer than metal, so a pair of nano-tweezers cut out of this paper could manipulate a single cell without puncturing it.
As a proof of concept, the Purdue researchers created a tiny magnetic lever, and the operated it by manipulating a magnetic field. Through that small demonstration, they showed how this material could be used to create a wide range of micromachines on the cheap. Additionally, the resulting lever was 100 times less expensive than an identical machine made out of silicon.
"It is very inexpensive to make," said Babak Ziaie, a professor of electrical and computer engineering and biomedical engineering at Purdue University. "You put a droplet on a piece of paper, and that is your actuator, or motor."
That is really cool!!!!!!!!!!!!!
Thhe title says "Nanomachine", but the article is more honest when is says they can make micromachines. There are several orders of magnitude difference.
Still cool though.
How big a sheet of paper would you need to make an engine for your electric car, and could I do it myself with a can of your ink?
You may not need to go that far, someone at CES just announced a color, 3D printer :)
The truth about nano technology is that we are probably about as far along with it as a monkey with a stick calling it a weapon of mass destuction.
they should next grow plant cells kill them until they are like paper fossils, then put the ink on them. that way you can control the design and make it realy smaller then what a nano scissor could do.
this is soo cool!
I don't believe there are too many of us out here that can really make or an informed comment of this technical progress. It is new technology and yes is very expensive. Unlike our wonderful sci-fi movies such as star trek the nanobots are become a closer reality and possibility for uses is endless.
nanomachines oh and magnetic ink that is a transformer! Very cool if it were to pass the stage of research. What other applications could this be used for, I am interested as there appears to be an impressive level of researchers involved in this programe. I do hope it is a progressive change and something that is worthwhile for mankind.
Wow! We are really moving into new fields of technology now. We have paper so strong that we can manufacture air craft and now we have Magnetic Ink. Oh it really is just a matter of time before those robots are household names.
