Writing with a Nanoscale Fountain Pen

Posted by timothy on from the I-would-like-this-for-postcards dept.

Roland Piquepaille writes "I'm sure that almost all of you have used a fountain pen. But imagine a pen drawing lines only 40 nanometers in width. Now, it can be done with the Nanofountain Probe (NFP) developed by scientists at Northwestern University. This innovative fountain pen "employs a volcano-like dispensing tip and capillary fed solutions to enable sub-100 nanometer molecular writing." But it needs to be mounted on an atomic force microscope (AFM) to be useful, so it probably is something you'll not find at your local drugstore for a while. However, this nanofountain probe could have applications for nanosensors, biotechnology and pharmaceuticals. Read more for other details, pictures and references."

    Just imagine the fine print that can be generated with this.

    "Well, if you closely examine this area that looks like an eyelash, you can almost see the thread of paper we used to write it on..."

    What are they going to do, write "Don't touch lens" or "Keep clean" or "Save the whales"? anyone know more descriptive uses?

    Also it must be a pain to put ink in.

    two year old research, repackaged and remarketed.

    Why do people insist on getting science from press releases? University press releases are one of the worst things to happen to the integrity of science. Of course it doesn't help that some people do so much to encourage them...
