‘DNA Microscopy’ Offers Entirely New Way to Image Cells
22nd June 2019
Now, biophysicist Joshua Weinstein and colleagues have invented an unorthodox type of imaging dubbed “DNA microscopy” that can do just that. Instead of relying on light (or any kind of optics at all), the team uses DNA “bar codes” to help pinpoint molecules’ relative positions within a sample.
With DNA microscopy, scientists can build a picture of cells and simultaneously amass enormous amounts of genomic information, Weinstein says. “This gives us another layer of biology that we haven’t been able to see.”
