Attack on a Single Cancer Cell Captured in 3D
“That white blob on the left is one of the ninjas living inside your body, a Natural Killer blood cell. This photograph shows it attacking a cancerous cell (on the right) in unprecedented detail.
The image was captured in 3D by an Imperial College London research team lead by Professor Daniel Davis. They used a completely new technique developed with the help of physicists and the college’s Photonics Group: optical laser tweezers combined with a super-resolution microscope.
Before this technique, microscopes captured multiple bi-dimensional slices and scientists stacked them up to create a 3D image. The process was slow, limiting the speed of the action. Furthermore, the resulting detail and resolution was poor.”
