What is self assembly? Few things in life are free. It usually takes parts and tools and some energy to build stuff. But can you imagine a bunch of parts assembling into something all by themselves? Do we have to go into a high-tech laboratory to see things that self assemble? Nah. It is all around you!
True or False. Scientists can move single atoms with nanometer precision. A scientist can point to atom and move it from here to there. The answer? True. True or False, the year that the scientists first moved individual atoms was the ... Read More...
The light from the thing that we want to see is magnified with lenses in a microscope and we see a virtual image of that tiny thing. The smallest thing that we can see with a ‘light’ microscope is about 500 nanometers. A nanometer is ... Read More...
How can we see a world that is too small to see? With our eyes, we can see the world around us because of the light that reflects off the object we are viewing. If we turn off the lights, everything becomes harder to see. ... Read More...
Nanoscientists use powerful microscopes called scanning probe microscopes to “see” atoms and molecules. In school or maybe at home you probably used an optical microscope. With those microscopes you can see cells. Scanning probe microscopes are a lot different than optical microscopes. Instead of using lenses and light ... Read More...
How do we know if a molecule has a shape? Well, there are various ways, but the most direct is to use a very powerful microscope like the atomic force microscope. That is what Seth Darling used to “see” his surfaces and all those shapes ... Read More...
