He l ed the group which developed the world’s most successful type of biosens or\, the hand-held mediated amperometric glucose sensor for people with di abetes. In November 2010\, he moved his research activities to Sweden to h ead the Biosensors and Bioelectronics Centre at Linköping University\, wh ile continuing to advise Cranfield University on innovation. He was electe d a Fellow of the Royal Society of Chemistry (1996) and awarded a Higher D octorate (DSc) for his exceptional contribution to biosensors by the Unive rsity of Kent (2001) and an Honorary DSc by the University of Bedfordshire (2008).  He was admitted to the USA National Academy of Engineering as a Foreign Associate in 2006\, for his work on glucose sensors\, environment al monitors and synthetic recognition molecules. He recently won the Theop hilus Redwood Medal\, from the Royal Society of Chemistry (UK)\, for his o utstanding contribution to Analytical Science\, and the Acharya Vinova Int ernational Award (India) for his “notable and outstanding contribution i n the field of Biosensors and Bioelectronics”. Professor Turner has >750 publications and patents in the field of biosensors and biomimetic sensor s and an h-index of 62. He co-founded and has edited the principal journal in the field\, Biosensors & Bioelectronics\, since 1985 and edited the fi rst textbook on Biosensors in 1987.  In addition to advising companies an d governments worldwide in the general area of analytical biotechnology\, he has served as an expert witness in patent litigations on three continen ts.\nThis lecture will consider how the recent emergence of printed bioele ctronics can offer new solutions to distributed diagnostics for the mainte nance of wellbeing\, management of an ageing population\, food security an d environmental safety.\nThe adaptation of screen printing for the product ion of enzyme electrodes proved to be a decisive element in the success of mediated electrochemical devices in the home blood-glucose monitoring mar ket. Until then\, biosensors had been wholly hand made\, and could not pos sibly address a market requiring billions of devices a year. Coupled with the use of proprietary mediators and patented capillary-fill designs\, mac hine fabrication of enzyme electrodes enabled the paradigm changing switch to the electrochemical devices that now dominate this market. Today\, app roximately half of the electrodes used in disposable glucose sensors are s creen printed using curable polymer inks\, while the remainder are produce d using a combination of vapour deposition of thin layers of metal such as palladium\, followed by laser ablation to pattern these into individual e lectrodes. Additional printing steps\, drop-on-delivery and /or lamination results in a final sensor\, which can cost around 2-6 US cents / strip to make\, when produced by the millions. However\, it is now timely to chall enge our original paradigm of a disposable strip coupled to a pocket-sized meter. Even in bulk\, the average meters cost between US$7-10 to manufact ure\, with some more elaborate versions costing as much as US$90.\nSo why not print the whole device? All-printed Mn –ZnO batteries can already be made to power microsensors and for other applications such as RFID tags\, transdermal drug delivery\, cosmetic patches and smart packaging. These a re available as commercial products such as the SoftBattery™ from Enfuce ll (Finland). Monochrome emissive or reflective digital displays can be pr inted on both paper and plastic and\, in keeping with the trend to interfa ce biosensing systems with telecommunication\, thin film aluminium or copp er antennae are also available. A state-of-the-art combination of these te chnologies allows us to formulate an all-printed sensing instrument where everything is produced on a simple sheet of PET to form a disposable\, cre dit-card like device. An example of such a working demonstrator resulting from collaboration between Acreo ICT AB and our team at Linköping Univers ity is shown below. Analyte concentration can be measured in a few seconds and observed via the printed display\, with the device being powered by a printed battery. This platform is being used to develop a range of new pr oducts incorporating nanomaterials\, principally for medical diagnostics\, but also for food safety analysis\, environmental monitoring and security applications.\nIn addition to reviewing the evolution of printing technol ogy in this arena\, this talk will explore the multifarious sensing config urations that can be supported by this inexpensive and disposable platform . Graphene-based hybrid structures\, unsubstituted phenothiazines and Prus sian blue nanoparticles have recently been incorporated into novel sensors for metabolites and physiologically important enzymes. Electrochemical im munosensors have also been formulated using silver nanoparticles and in la bel-free formats. Gold nanoparticles and nanostructured gold surfaces prov ide further functional enhancement and smart polymers can add reversibilit y to affinity systems and modulation to catalytic configurations. Finally\ , synthetic receptors based on imprinted nanoparticles offer robustness be yond that normally achieved with biological components. The combination of advanced synthetic materials with biologically inspired constituents prom ises 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 avail able and rapidly evolving.
