Professor Marija Drndić and her team have just published results on realizing a new sequencing technique based on threatind a string of DNA through a tiny hole and using a nearby sensor to read each letter as it passes through an atomically thin layer of carbon called graphene. The team's latest study shows how to drill nanoporers, the tiny holes, without ruining graphene's electrical sensitivity, a risk posed by simply looking at the material through an electron microscope.
