A NOVEL HIGH PERFORMANCE MICROFLUIDIC CARTRIDGE FOR BIOSENSOR/IMMUNOSENSOR APPLICATIONS

摘要

A microfluidic cartridge device incorporating a microfluidic substrate and a gold-sputtered thin film biosensor substrate is disclosed, for biosensor and immunoassay applications. The sensor layer incorporates an electrochemical sensor formed by laser scribing. The microfluidic substrate comprises a double-sided adhesive layer in which the microfluidic channels are formed by laser cutting. The device further integrates micropumps to facilitate washing and access to immunosensor reagents.
