Nano Mona Lisa

Much in the same fashion as the nanoguitar, which was made in 1997 by the Cornell NanoFabrication Lab, scientist have continued the craze of real, tiny objects by making a nano Mona Lisa, where each pixel is 125nm in width and length..

Mona Lisa

This Mona Lisa, which is 30 microns in width, was made by controlling the number of molecules in each pixel. They did this by either heating each pixel (which would increase the concentration and make a lighter cool) or decreasing the temperature (which would do the opposite). 

This has been concluded to being the easiest way to manipulate molecules, nanoparticles, and other materials. It is also advantageous because atomic force microscopes (which were used in making it) are fairly common, making this an effective method in industrial and educational labs.

ALD NanoSolutions

This company is the heart of Nanotechnology and everything that it stands for. This company is presenting ideas that were not thought to be possible a few years ago, and is creating jobs that did not exist before.
ALD NanoSolutions makes individual atoms adhere to themselves and other atoms, at our will. This obviously opens the possibility of using properties only available at the nanoscale. Normally, this process takes a long time, but ALD has perfected the procedure, and is now able to do it almost instantly, by utilizing gas deposited and reactions. They are able to make aluminum oxide, a nanoparticle that is capable of blocking UV radiation (so it is used for sunscreens),  of being used as a catalyst, cosmetics, paint, as an abrasive, and as a way to remove water from a gas stream. They make the particle by layering an aluminum compound onto an oxygen containing compound, and do so sereveral times to make an atomically thin sheet.

This is an excellent resource for those interested in going into nanotechnologies. It is a map created by the National Nanotechnology Initiative, and is useful to find the number of Nanotechnology programs in your individual State. Specifically, it says the number of PHD, Master, Bachelor, programs and the Schools and Training Programs, NNI Centers and Networks of Excellence Regional, State, and Local Initiatives in Nanotechnology.
