dc.description.abstractThe fabrication of laser-induced graphene (LIG) allows rapid, inexpensive patterning of electrode designs onto various substrates. LIG is a material whose properties can be tuned by altering the fabrication process, to suit the desired application. In this thesis, LIG materials were developed using a low-power hobbyist visible laser system, for electrochemical sensing applications. Polyimide (PI) was studied initially as a precursor, with the resultant LIG electrodes showing excellent electrochemical properties. Then LIG electrodes were bio-modified for the sensitive detection of Interleukin 6. Bioplastic precursors, as an alternative to PI, were explored as a potential route to green-LIG devices. Chitosan-based sheets were graphitised, and the properties of this LIG were investigated. The electron transfer rates at such electrodes are promising for future device applications. Finally, cork is used as a LIG precursor. Electrochemical cork-LIG sensors showed remarkable properties, with rapid electron transfer rates and a low detection limit for Tyrosine and dopamine. The results contained in this thesis present fast, inexpensive and eco-friendly options for LIG electrochemical sensor development.en
