Description

This protocol details the fabrication of a 2 layer PDMS device, consisting of a valve layer (top) and channel layer (below). It is assumed that masters for respective layers have already been fabricated (see Godin:Protocols/SU-8 Master, Godin:Protocols/AZ Master). The idea is to modify the silicone elastomer base to curing agent ratio, thereby modifying PDMS elasticity.

Valve Layer

  • Mix PDMS 7:1


  • 30 min degass
  • 12 min @ 80°C
  • Punch valve holes
  • Cleaning

Fluidic Layer

  • Mix PDMS 20:1
  • 30 min degass
  • Spin coat
  • 10 min @ 80°C

Device Fabrication

  • Alignment
  • >2 hrs @ 80°C
  • Punch fluidic holes
  • Cleaning
