AB  - A novel protocol for fabrication of micro gold devices on poly(dimethylsiloxane) 
      (PDMS) substrates was developed on the basis of region-selective electroless 
      plating. The layout of a micro gold device was first photochemically patterned 
      onto the PDMS surface through a UV induced poly(acrylic acid) (PAA) grafting 
      process. The carboxylic moieties on the grafted PAA served as the scaffold for a 
      series of wet chemical reactions that led to the immobilization of gold 
      nanoparticles in the UV-exposed region, where electroless plating then occurred 
      under the catalysis of the nanoparticles. Gold devices fabricated with such a 
      protocol could tolerate the Scotch tape test and survive in a repeated 
      bending-straightening test. They also showed good stability in acidic and 
      alkaline solutions, possessed almost the same electrochemical properties as a 
      standard gold disk electrode, and allowed thiol-compounds to form a perfect 
      self-assembled monolayer on their surfaces. The fabricated micro gold electrode 
      was demonstrated to be suitable as the integrated amperometric detection element 
      in a full PDMS micro electrophoresis chip.
