Overview

Organic electronic devices are flexible, light weight and stretchable, which makes them an ideal candidate for integrating and interfacing with soft tissues in biological systems. An attractive attribute of organic electronic devices is the solution processibility of constituent layers, since solution-processable devices have the potential to be printed into complex designs and shapes, leading to integrated devices with multiple functionalities. Particularly, organic thin film transistors (OTFTs) have the potential to offer low cost, easy to use and printable sensors for a variety of applications such as chemical sensing, explosive sensing, etc. Additionally, OTFTs have shown great promise for applications in biosensing and interaction with the biological world. For instance, OTFTs have been successfully used in in vivo recordings of brain activity, reagentless immunosensing and label-free DNA sensors.

This project aims to explore OTFTs and develop OTFT designs for advanced sensing platforms that will have applications in lab-on-a-chip technologies, biointerface electronics and bionics. This is an experimental project. Once a specific structure of an OTFT is established, the various components of an OTFT will be deposited either by solution processing or by vacuum thermal evaporation. It will involve extensive experimental work using a variety of sophisticated equipment, including a system of glove boxes which has capacity for fabrication of organic electronic devices in an inert environment, in the Central Analytical Research Facility, Gardens Point. All characterisations of OTFT and complete analysis of critical parameters will be carried to study the possibilities of using the developed OTFT for sensing applications.
