DESCRIPTION:Atomically thin nanopore membranes are considered to be a prom
 ising approach to achieve single\nbase resolution with the ultimate aim of
  rapid and cheap DNA sequencing. Recently\, we made advances in\nusing nan
 opore platform for its integration with 2 D materials such as graphene or 
 MoS2. Translocation of\nvarious types of DNA exhibits a signal amplitude t
 hat is five times higher than in the case of solid-state\nSi3N4 membranes 
 and a SNR of more than 10. Although single nucleotide identification and D
 NA\nsequencing using biological pores have already been demonstrated their
  fragility\, difficulties related to\nmeasuring pA-range ionic currents to
 gether with their dependence on biochemical reagents\, make solid\nstate n
 anopores an attractive alternative.\n\nIn this talk I will address novel a
 pplications that address identification of single nucleotides but as\nwell
  go beyond DNA sequencing. We use novel solid state nanopore platform base
 d on atomically thin\nnanopore membranes in 2D materials such as graphene 
 or molybdenum disulfide for DNA detection\,\nsequencing\, water desalinati
 on and osmotic power generation.
