Sabine Schmidt from ISAT at Coburg University reports on the use of plasma in microfluidics to achieve a connection between PDMS and glass substrate.
The surface treatment of glass with plasma has been established in practice for many years. There are many different fields of application. For example, cold atmospheric pressure plasma is used to improve adhesion between glass and PDMS. Another example is the preparation of glass for digital printing. This is particularly important because glass is very difficult to print without pre-treatment and the print result often leaves a lot to be desired.
