Powerful optical imaging technology catches DNA naturally fluorescing

Posted on Updated on

Biomedical engineers have developed imaging technology that is the first to see DNA ‘blink,’ or fluoresce. The tool enables researchers to study individual biomolecules (DNA, chromatin, proteins) as well as important global patterns of gene expression, which could yield insights into cancer. Many of the secrets of cancer and other diseases lie in the cell’s nucleus. But getting way down to that level to see and investigate the important genetic material housed there requires creative thinking and extremely powerful imaging techniques.
