In this research, on-chip cell analysis platform for integrating contact fluorescence microscopy was performed using microfluidic chips. In microfluidic device fabrication, PDMS and ultra-thin glass substrates were bonded using exposure to oxygen plasma. Samco RIE etcher was used for oxygen plasma treatment of the substrates.

Samco offers plasma treatment technologies for microfluidics fabrication. Unique plasma processes enable plasma bonding of substrates such as COP and glass without microchannel pattern collapse because there is no need to implement mechanical pressing and heating for bonding.
