The plasma treatment is the best solution to get long-term surface activation. The chemical reactions involved create a covalent bonding between PDMS-PDMS or PDMS-glass surface. Moreover, it can be used to remove contaminants of a surface thanks to its high oxidative power.
The Plasma Cleaner is provided with a vaccum pump and a gas flow mixer that monitors vaccum pressure.
It is included in the Microchannels Fabrication Kit to ensure a strong bonding between the microchannel PDMS chip and the glass bottom petri dish. Once this step is done, the great hydrophilicity enables an easy loading of extra cellular adhesion proteins and cell solutions into the microchannels.
