Argonne biologist Rosemarie Wilton works on ways to stabilize antibodies, which tend to degrade over time.
Antibody builders

Because antibodies are naturally so good at recognizing a host of different pathogens, Argonne biologist Rosemarie Wilton has spent much of her career working to better stabilize antibodies and prevent them from degrading over time.

A high-resolution transmission electron microscopy image of the core of a single silver nanowire. The scale bar represents 5 nm in length.  The image was taken on the Argonne Chromatic Aberration-corrected TEM (ACAT) machine.
Sterling science: Strain in silver nanoparticles creates unusual “twinning”

When twins are forced to share, it can put a significant strain on their relationship. While this observation is perhaps unsurprising in the behavior of children, it is less obvious when it comes to nanoparticles.
