The Biosensor Platform

The Biosensor Platform

The Biosensor is a Platform for Multiple Diagnostic Tests

World-first Organic Thin Film Transistor (OTFT) technology.

The Biosensor Platform is a small, printable organic strip designed to put the power of accurate, timely diagnosis in the hands of patients and their primary health practitioners.

By altering the detection element (region A) depending on the specific analyte of interest, we can produce a complete portfolio of non-invasive, real-time, saliva-based diagnostic tests.

Because both the core OTFT sensing element and the mechanism of action remain the same, tests developed from the Biosensor Platform have the potential to be printed at scale and low cost.

About the Centre for Organic Electronics

The University of Newcastle

The biosensor was invented at the Priority Research Centre for Organic Electronics at The University of Newcastle, Australia.

The Centre for Organic Electronics is the first of its kind in Australia. It is an exciting new initiative focusing on the development of new electronic devices at the intersection between semiconductors and plastics.

The Centre focuses on the scientific challenges in the development of organic electronics, with massive potential for the next generation of environmentally friendly energy sources, photonics and biosensors.

Future Tests

Development has commenced on an complete portfolio of tests including cancer markers, hormones and allergens.
