Pull with caution
Trieste, Italy (SPX) Nov 15, 2012
As nanotechnology progresses, it becomes increasingly important to know in detail the dynamics of the nanoworld (the world at the scale of a millionth of a millimeter). What happens, for example, when we try to drive a polyelectrolyte (a long chain of electrically charged molecules, such as DNA) through a nanopore if knots cause the translocation process to jam? It's not a pointless question, because now a new DNA sequencing method to electrochemically analyze every single strand by driving it thr ... read more
