PDMS chip microfabrication
In our molding setup, the microfabrication of PDMS chips is performed outside of a clean room. Initially, PDMS is mixed with a curing agent and degassed in a desiccator. Then, the elastomer is poured onto a mold and cured in a conventional oven. Following curing, the chips are demolded, accurately cut, and inlet perforations are created using biopsy punchers. Lastly, the PDMS is firmly fixed to a glass slide following its treatment in a plasma cleaner.

However, due to PDMS limited chemical compatibility, high gas permeability, and low throughput, researchers started looking for replacement materials with better properties, such as thermoplastics.
Switching to Polycarbonate (PC) molding
Polycarbonate (PC) is an optically transparent material, allowing for easy visualization and monitoring of fluids within microfluidic channels. In addition, it’s a durable and rigid thermoplastic material with high mechanical strength. Notably, this material is known for its excellent wide-range chemical resistance, biocompatibility, and commercial availability, which makes it adapted for mass manufacturing. Furthermore, PC is thermally stable, which confers resistance to elevated temperatures during fabrication processes and experimental operations on the fabricated microfluidic chips.
Overall, the combination of transparency, mechanical strength, chemical resistance, thermal stability, biocompatibility, and commercial availability makes polycarbonate a versatile and attractive material for fabricating microfluidic chips.
Polycarbonate microfabrication follows the same steps as thermoplastic chip microfabrication, and both can be performed outside of a clean room.

By integrating our recommended heat press and laminator into your workflow and adhering to our guidelines, you can seamlessly transition from PDMS microfabrication to PC material molding setup.

Frequently asked questions
Does the process also involve mold fabrication?
Currently, the polycarbonate (PC) molding microfluidic setup focuses on the chip fabrication and bonding from a pre-existing mold. However, we do have expertise to advise you in how to make your own molds.
What is the resolution of the Polycarbonate microfluidic devices?
Resolutions as low as 15 µm (channel width) for an aspect ratio of 2:1 can be achieved.
What maximum pressure can the devices withstand?
Based on internal testing, up to 3.5 bar.
What material can I use to close the chip?
The chip can be closed with a thermoplastic slide, a microscope glass slide or a microscopy-compatible polymer slide.
Is this process compatible with microscopy/reversed microscopy?
Polycarbonate is optically transparent and well-adapted to microscopy.
