Device Materials

We work with a variety of materials for microfluidic chip fabrication

We have core expertise in the development and proprietary technology for fabrication of microfluidic devices made of a variety of material systems. Materials for microfluidic chip fabrication include:

  • PDMS or polydimethylsiloxane is a rubber-like medical grade silicone.

**PDMS is the most widely used silicon-based organic polymer, and is particularly known for its unusual rheological (or flow) properties. PDMS is optically clear, and, in general, inert, non-toxic, and non-flammable.

 

  • Thermoplastics such as:
    • PMMA – Polymethyl methacrylate, a.k.a acrylic glass or Plexiglass.
    • PC – Polycarbonate, such as Makrolon or Lexan.
    • PS – Polystyrene, popular plastic used for cell culture containers such as Petri Dish.
    • COC – Cyclic Olefin Copolymer, is a thermoplastic polymer.
    • COP – Cyclic Olefin Polymers, is a thermoplastic polymer.

  • Glass-PDMS

**Since PDMS parts have rubber-like mechanical properties, they are not stiff enough for handling especially when the parts are less than 1 mm (0.04”) thick. Therefore, these PDMS parts are often bonded to glass microscope slide or thin glass cover slide, or even custom size glass substrates. Sufficient bonding strength between PDMS and glass is needed for continuous flow applications, otherwise the fluid would leak out of the microfluidic channels. uFluidix has special expertise in bonding and sealing PDMS parts to glass and variety of other substrates.
