Microfluidic


What are microfluidics?

Microfluidic systems deal with the behaviour and control of liquids in very small channels - usually in the micrometre range. In such systems, tiny quantities of liquid can be precisely moved, mixed or analysed.

Injection moulding of microfluidics

Our extensive expertise in the production of precision parts enables us to reliably mould the finest structures of microfluidics. Frequently used materials for the production of microfluidics are PMMA (e.g. 7N, Cyrolite), COC (e.g. Apel, Topas) and COP (e.g. Zeonex).
Polymeroptix develops/tests and manufactures your microfluidic design or your microfluidic idea. We use mould inserts with lithographically and machined microstructures/microfluidics from competent partners.
Depending on the application, we use injection moulding or injection compression moulding to achieve the best possible quality. We have our own interchangeable tool with which initial moulded parts and series parts can be produced cost-effectively. Very fine structures can also be moulded using inductive variothermal heating (with vacuum support on request).
Our own analytical equipment includes a profilometer, profile projector, coordinate measuring machine and various microscopes.
 

Areas of application:

  • Lab-on-a-chip systems (LoC)
    Plastic-based microfluidic chips are used to miniaturise and automate chemical and biological analyses, e.g. in medical diagnostics (blood analysis, PCR tests).

  • Point-of-care diagnostics
    Portable rapid test systems for e.g. infectious diseases (such as COVID-19 or HIV), pregnancy tests or blood glucose measurements are often based on plastic microfluidic structures.

  • Environmental analysis
    Microfluidic plastic systems enable mobile and cost-effective testing of water, air or soil samples for the detection of pollutants, heavy metals or pathogens.

  • Pharmaceutical research and drug development
    Microfluidic platforms are used to synthesise, mix and test active ingredients in very small volumes, thereby reducing costs and time in drug development.

  • Cell and tissue culture ("organ-on-a-chip")
    Plastic-based microfluidic systems simulate physiological conditions in miniature formats in order to investigate cell behaviour, toxicity or drug effects.

 

Advantages of plastic microfluidics:

  • low production costs
  • compact design
  • low reagent consumption
  • fast reaction times
