DESCRIPTION:The possibility to apply microelectronics and nanotechnologies
  to biological applications has driven the development of a class of devic
 es know as BioMEMS. In these devices\, electronic\, electromechanical and 
 microfluidic elements can be combined to allow sensitive\, automated and\,
  potentially\, portable biomedical devices. Our research at INESC MN cente
 rs on the application of thin film electromechanical and electronic device
 s to biological sensing applications. \n\nIn this talk\, we present an ove
 rview of two aspects of this work:\n\n- Electric-Field addressing of biomo
 lecules:\nIn this work\, a single\, fast\, electric field pulse is used to
  significantly enhance the kinetics of DNA immobilization and hybridizatio
 n\, as well as protein immobilization\, on a functionalized thin-film surf
 ace. We will also discuss how this can be applied to fabrication and analy
 sis of DNA microarrays.\n\n- MEMS-based biomolecular detection: \nWe will 
 describe the fabrication and properties of thin-film silicon and polymer m
 icroelectromechanical systems\, and their application as molecular biosens
 ors for on-chip detection of DNA and proteins.\n
