Since the earliest microscopes, scientists have been on a quest to build instruments with finer and finer resolution to image a cell’s proteins – the tiny machines that...

The College of Chemistry has received a new state-of-the-art EVO LS 15 scanning electron microscope (SEM) provided by ZEISS in support of the instructional physical chemistry labs. The new SEM will allow our students to take images of...
When scientists use superresolution microscopy methods on cells, they usually get just structural information like the sizes and shapes of cellular compartments. By using a new derivative of a conventional dye, researchers can now get specific nanoscale information about the chemical environment of cell plasma membranes. Such information could tell scientists about the order and disorder of the cell membranes, including about highly ordered “lipid rafts.”
