Shine a Light: High-Resolution Microscopy and Imaging in Biology

Shine a Light

Posted March 09, 2009


Innovations in light and electron microscopy and biological imaging are a foundation for experimental biology. At the January 29, 2009, meeting of the Soft Materials Discussion Group, scientists described new approaches for imaging cellular events and the contributions of existing methods on the front lines of epidemics.

Jennifer Lippincott-Schwartz of the National Institutes of Health began with a discussion of developments in photoactivatable protein technology. Biomedical engineer Maribel Vazquez of CUNY's City College described work on a nanomicrofluidic system that monitors both cellular movement and intracellular signaling in response to external factors. Charles Humphrey of the U.S. Centers for Disease Control in Atlanta described his work with negative stain transmission electron microscopy (TEM), a decades-old technique that is still the fastest way to identify emerging viral pathogens.
