Science even when it is serious is kind of funny.  Looking at things on the nanometer-scale is a problem and requires very powerful microscopes.  Some of these microscopes that use electrons instead of light are able to see very small things but also usually kill anything that it ‘sees’.  Basically the electron beam dries out the cells and leaves those critters dead.  Scientists at the Japan Science and Technology Agency have devised a clever solution—coat the living thing that you want to see in a polymer suit.  These nanosuits are made of a polymer and some detergent but it is flexible and protects the critter while it is being zapped with electrons. Because the nanosuit is polymerized right on the critter, it is a nice custom fit. Oh and does it come in colors?  of course not because at the nanometer-scale there is no color.
