DESCRIPTION:DNA nanotechnology is transformative for experiments that requ
 ire molecular control over the shape of nanometer-sized objects. In combin
 ation with nanopores\, DNA self-assembly allows for novel experiments that
  reveal the physics of ions\, and polymers on the single-molecule level. \
 n\nNanopore sensing\, best known for DNA sequencing\, translates the three
 -dimensional structure of molecules into ionic current signals. Designed D
 NA molecules enable multiplexed protein sensing with an all-electrical app
 roach. Here\, Professor Ulrich Keyser will discuss his group's recent deve
 lopments to detect and localize structures as accurately as possible along
  DNA molecules approaching super-resolution microscopy. The localization i
 s enabled by a quantitative understanding of polymer dynamics in our glass
  nanopores which enables it to extract position information to a few ten b
 ase pairs. In the last part of the talk\, he will explain how we used our 
 knowledge on single-molecules and nanopores to crate a novel test for viru
 ses and their variants that may play a role in (the prevention of) future 
 pandemics. \n
