MICROFLUIDICS

 

The study of microfluidics may either serve to replicate real-world reactions or enable detection of smallest amounts of substances. A prime example is the “lab-on-a-chip”: Chemical or biological reactions are “miniaturized”, thereby enhancing efficiency and enabling application in constricted conditions. Some microfluidic chips serve as sensors, while so-called “bio-chips” are used for protein or DNA analysis, or allow for diagnostics of microscopic blood samples.

Requirements

  • Surface smoothness
  • Large structures
  • High aspect ratio
  • Straight walls

APPLICATION IMAGES

 

Microfluidic mixer

The image shows a master of a microfluidic mixer in 100 μm SU-8, which can be patterned with the 375 nm wavelength option of the MLA150. This type of structure is typically transferred by soft lithography in PDMS.

Microfluidic device

Another type of microfluidic device patterned by direct write lithography.
