Viruses are ubiquitous: for every organism, there are multiple viruses that can infect it. Although we know much about the beautiful structures of viruses, and we understand how certain viruses (the ones that are bad for us) infect a cell, we know little...

To make a material that is colored, one normally uses a dye or pigment. But another way to make color is to make a nanostructure that reflects or scatters light so that waves of certain frequencies can constructively interfere. These nanostructured...

Using digital holographic microscopy, we study how colloidal particles bind to oil-water interfaces. Small particles have a natural affinity for interfaces, and this affinity can be used to control their self-assembly and make some interesting materials...

We use a fast imaging method called holographic microscopy to watch self-assembling systems. In a holographic microscope, the sample is illuminated by laser light, and the resulting image (or hologram) can be used to determine the 3D structure, position...
