A disposable electrochemical immunosensor is disclosed that is made of a gold sputtered polyester substrate formed using laser ablation and overlaid with adhesive spacer to define the electrode areas. The disclosed immunosensor has nearly 3 times the sensitivity of conventional carbon screen printed electrodes, has ...

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 adh...
