PROTOCOLS
Microfluidics
PDMS (Polydimethylsiloxane) is a widely used polymer in microfluidics, for its biocompatibility and transparence, among other qualities. Here we show how to prepare PDMS for microfluidic chips, as well as how to demold them, bond them to other surfaces and treat them for neuron growth.
PDMS Chips Fabrication
PDMS Chip Demolding
Materials
- Sylgard 184 Elastomer Kit (Sigma-aldrich, Sylgard 184, 761036-5EA)
- Vacuum pump unit (Vacuubrand PC 3 RZ 2.5)
- Stove (Memmert UM 400)
Protocol
According to manufacturer's instruction.
- Mix monomer and curing agent (10:1 proportion) for 30 seconds
- Use a vacuum pump unit and a vacuum bell jar to extract air bubbles until the mixture is clear
- Pour mixture onto mold
- Put mixture+mold in stove at 70 degrees Celsius for 3 hours
