New imaging technique reveals unprecedented nanoscale details about DNA.


A strand of DNA is a very long, narrow string, just a few nanometers across. Single-molecule orientation measurements provide unparalleled insight into a multitude of biological and polymeric systems.  Single-molecule microscopy, together with fluorescent dyes that attach to DNA, can be used to better visualize this tiny string. However, it is difficult to understand how those dyes are oriented and
