Conditions for the groth of biological specimen can be influenced by plasma treatment. Therefore the microtiters used for biological experiments are plasmatreted before use.
Plasma can operate in molecular dimensions
Microfluidic components with channels, valves and pumps with dimensions in the magnitude of 1 µm can be generated by anisotropic plasma etching. A mould of fotoresist generated by fotolithography is copied by PDMS (silicons) If the mask is plasma etched, structures may be below 1 µm.
The PDMS modell when cured can be bonded without any glue to PDMS, glass or silicon by treating both surfaces to be connetcted by oxygene plasma.
