SUMMARY:DNA in Nanoscale Electronics – Jason Slinker\, UT Dallas
DESCRIPTION:Jason Slinker\, Department of Physics\, University of Texas at
  Dallas\, Richardson\, TX\, USA DNA\, possesses a number of attractive p
 roperties for use in nanoscale circuits\, and charge transport (CT) throug
 h DNA itself is of both fundamental and practical interest. Fundamentally\
 , DNA has a unique configuration of π-stacked bases in a well ordered\, d
 ouble helical structure. Given its unparalleled importance to life process
 es and its arrangement of conjugated subunits\, DNA has been a compelling 
 target of conductivity studies. In addition\, further understanding of DNA
  CT will elucidate the biological implications of this process and advance
  its use in sensing technologies. We have investigated the fundamentals of
  DNA CT by measuring the electrochemistry of DNA monolayers under biologic
 ally-relevant conditions. This approach has uncovered both fundamental kin
 etic parameters to distinguish between competing models of operation as we
 ll as the practical implications of DNA CT for sensing. In collaboration w
 ith the UT Southwestern Simmons Cancer Center\, this understanding has bee
 n used to create a new biological assay of DNA damage repair and anticance
 r drug activity. Furthermore\, we are leveraging our studies of DNA conduc
 tivity for the manufacture of nanoscale circuits. We are investigating the
  electrical properties and self-assembly of DNA nanowires containing artif
 icial base pair surrogates\, which can be prepared through low cost and hi
 gh throughput automated DNA synthesis. This unique and economically viable
  approach will establish a new paradigm for the scalable manufacture of na
 noscale semiconductor devices. Site web du groupe du Prof. Slinker'sCette
