Microfluidic Coating Technology

Our microfluidic coating treatments enable creation of microfluidic patterns on nearly any surface without damming or physical barriers. Options include hydrophilic and/or repellent (hydrophobic/oleophobic) surface functionalization coatings which can be utilized to create together or independently to create finely detailed microfluidic patterns. Solutions are easy-to-apply scalable treatments that can bond with a wide array of surfaces. Together we create winning microfluidic devices!

Microfluidic Surface Treatments. Eliminate Physical Barriers. Liquid Repelling or Attracting.

Aculon® has a variety of surface coating technologies capable of functionalizing countless substrate types to have microfluidic channels. This can be accomplished without traditional physical patterning that requires cutting pathways or addition of physical dams. These ultra thin microfluidic treatments allow for less complexity and far smaller package sizes without the added design requirements of physical chanelling. Both Repellent (hydrophobic & oleophobic) and hydrophilic (water attracting) technologies are available and can be utilized independently or in conjunction with each other to create the desired effect.  Used in combination with specialized deposition equipment allows for extremely fine and detailed patterns.

Would your microfluidic application benefit from from utilizing nanoscale surface coatings?

Thin-film surface coating technologies can be used to address a wide variety of microfluidic challenges. Some examples below where an surface modification coating will help improve the quality of your product.

  • Package design does not allow for thickness of physical patterning.
  • Material is wicking outside of desired pathways.
  • Material is not wicking in areas as desired.
  • Rapid pattern flexibility without need to retool is desired.

Microfluidic Coating Platforms

Our repellent technologies for microfluidic components will yield a robust and long lasting hydrophobic and oleophobic surface. Typical water contact angles (measurement of surface energy) are in the 115°-120° range and typical oil contact angles are in the 75°-85° range. These treatments are nanoscale, as thin as 2-4 nm thin leaving your part visually unchanged and optically clear. These materials can be applied via specialized selective deposition and patterning equipment to achieve finely detailed microfluidic pathways. A self assembling process ensures a uniform and even treatment every time!

Our hydrophilic technologies are thin and optically clear and will yield a robust and long lasting hydrophilic surface. Typical water contact angles (measurement of surface energy) are in the <10° range. Common uses include creating water wetting surfaces that will draw liquids to desired areas. These materials can be applied via specialized selective deposition and patterning equipment to achieve finely detailed microfluidic pathways. A self assembling process ensures a uniform and even treatment every time!
