Microfluidics is a rapidly expanding field and microfluidic devices are used in many different areas including biotechnology, chemical analysis and medicine. Microvalves are often one of the building blocks required to complete a successful microfluidic device. They carry out a variety of functions including containing fluids, regulating flows, and isolating one region from another in a microfluidic system.
PDMS microvalves are now being made. But on plastic microfluidic devices, the microvalve has many challenges. The bonding between plastic and other material is one of the key challenges.
In this talk, IMG member Pan Gu will introduce some bonding issues and demonstrate how to realize a microvalve on a plastic microfluidic device. The discussion will include:
- PDMS/plastic bonding.
- PU/plastic bonding
- Realizing Quake’s valve and thermal actuated valve on a totally plastic device.
