By controlling this process precisely and measuring the change in ionic current as the DNA strands move through the pore of the membrane, the sequencer can read each base pair in order.
"Stampede is by far the best computer system my group has used over the past 10 years", Aleksei Aksimentiev stated. "Being able to routinely obtain 40-80 nanoseconds of molecular dynamic simulations in 24 hours, regardless of the systems' size, has been essential for us to make progress with rapidly evolving projects."
Aleksei Aksimentiev and his group showed that localized heating can be used to stretch DNA, which significantly increases the accuracy of nanopore DNA sequencing. In addition, he and his team used an all-atom molecular dynamics method to accurately describe DNA origami objects, making it possible to engineer materials for future applications in biosensing, drug delivery and nano-electronics. These results were published inACS Nanoand theProceedings of the National Academy of Sciences.
