Ok, so this isn't a new microscopy technique. However, electron microscopy is used to image these beautiful and tiny artificial flowers. They are created by combining two materials and then altering the conditions. What is cool is that the conditions for certain shapes using these materials has now been fairly well determined, which means we can build designs such as flowers by altering the conditions in a determined manner. This will enable scientists to grow materials to set specifications and shapes at a very small scale.
