Selective modification for polydimethylsiloxane chip by micro-plasma

We report a method to selectively modify polydimethylsiloxane (PDMS) chip in a fast and facile way using micro-plasma approach in the atmospheric-pressure. Pure He and He/acrylic acid plasma were ignited directly in different channels of PDMS microchip. Our experiments results yielded strong hydroph...

Zusammenfassung:	We report a method to selectively modify polydimethylsiloxane (PDMS) chip in a fast and facile way using micro-plasma approach in the atmospheric-pressure. Pure He and He/acrylic acid plasma were ignited directly in different channels of PDMS microchip. Our experiments results yielded strong hydrophilic property on the surface of PDMS by the plasma treatment.
