Polymers are the most popular materials for the fabrication of microfluidic devices. However, proteins tend to adsorb to these materials, causing biofouling. Moreover, commonly used thermoplastics such as COC (Cyclic Olefin Copolymer) are hydrophobic, thus hampering capillary flow of (biological) liquids.
Surfix offers nanocoating-enabled microfluidics with hydrophilic, antifouling surface properties by (local) control of wettability and biomolecular interactions.
Moreover, combining coating with bonding (‘closing’) of the chip in a scalable manufacturing process is a persistant challenge in microfluidics. Surfix's Coat & Close technology integrates coating and bonding in a single process, resulting in strongly bonded devices with hydrophilic, antifouling surfaces.
