| This thesis describes a simple micro-patterning technique using a conventional desktop inkjet printer with no modifications. The technique demonstrates patterning of gold sputtered recordable compact discs (CD-Rs) and printing of phospholipid films on top of the patterned gold electrodes to configure an iodine vapour sensor.;Long-chain alkanethiols were used as masking layers, and they were applied to the gold-coated side of CD-Rs using an inkjet printer. This step was followed by wet-chemical etching to realize a set of interdigital gold electrode pair. Subsequently, a thin film of phospholipids was selectively deposited on top of each electrode pair, transforming it to serve as a conductometric chemical sensor unit. These units were then exposed to iodine vapour, and the electrical response was documented to successfully demonstrate the functionality of the sensor. This technique outlines a generic approach for producing disposable multiplex biosensor and portable electrochemical analyzer rapidly and economically. |
