TI  - Electroosmotic flow in a poly(dimethylsiloxane) channel does not depend on 
      percent curing agent.
PG  - 1120-4
AB  - Poly(dimethylsiloxane) (PDMS) microfluidic devices were prepared from different 
      ratios of "curing agent" (which contains silicon hydride groups) to "base" (which 
      contains vinyl-terminated noncross-linked PDMS), to determine the effect of this 
      ratio on electroosmotic flow (EOF). In fabricating devices for this purpose, a 
      novel method for permanently enclosing PDMS channels was developed. As a 
      supplement to the microfluidic method, the inner walls of capillaries were coated 
      with PDMS formed from varying ratios of curing agent to base. EOF was found to be 
      constant for PDMS formed with each ratio, which implies that the negative surface 
      charges do not arise from chemical species present only in the base or the curing 
      agent.
