Abstract
The effects of radio frequency (RF) argon (Ar) and oxygenated argon (AO) plasma on the surface chemistry of TopasR Cyclic Olefin Copolymer (COC), have been investigated. This is necessary because the hydrophobic nature of COC can lead to adsorption of specific compounds from biological fluids channel which can impair precise quantification and cause clogging. Attention was paid to sample storage conditions between treatment and analysis. Hydrophilization at plasma power ratings of 100 W with exposure times from 60 s to 240 s were carried out. The surface roughness was characterized using atomic force microscopy (AFM) and wettability was determined using contact angle measurements. The influence of plasma treatment on the integrity of thermally sealed microdevices was assessed using burst pressure tests. The electro-osmosis flow in the plasma treated microchannels was also investigated. © 2011 Elsevier Ltd. All rights reserved.
