Printed Biosensor Devices for mHealth

The adoption of screen printing for the production of enzyme electrodes proved to be a decisive element in the success of home blood-glucose monitoring. Until then, biosensors had been wholly hand made, and could not possibly address a market requiring billions of devices a year. Coupled with the use of proprietary mediators and patented capillary-fill designs, machine fabrication of enzyme electrodes enabled the paradigm changing switch to the electrochemical devices that now dominate this market. Today, approximately half of the electrodes used in disposable glucose sensors are screen printed using curable polymer inks, while the remainder are produced by vapour deposition. Further advances in 3-D printing and printed electronics now make it timely to consider printing not just the senor, but the entire instrument. This talk will explore a state-of-the-art combination of these technologies in the form of an all-printed sensing instrument where everything is produced on a simple sheet of PET to form a disposable, credit-card like device. This platform is being used to develop a range of new products, principally for medical diagnostics, but also for food safety analysis, environmental monitoring and security applications. The combination of advanced semi-synthetic and synthetic receptors with nanomaterials, promises to facilitate a growth in personalised analytical solutions that are widely available to the consumer and that can capitalise on the ubiquitous telecommunications and information systems that are now both widely available and rapidly evolving. The convergence of technologies taking place at the moment prompts a radical rethink of how we deliver healthcare and support currently, and paves the way for a much more person-orientated service that takes into proper account individual physiology and empowerment in a new outcomes-driven paradigm.
