Integrated printed biosensor platforms

There is a need for robust disposable sensor systems that are easy to use and manufacture. Application areas could be point of care, food safety, environmental monitoring and agriculture.

Printed electronics has emerged as an exciting technology, as a complement to silicon based electronics, that today enables printing of materials and electronic devices, such as power sources, biosensors and displays, for different types of applications. Two recent publications demonstrating possibilities with printed electronics is the flexible active matrix addressed display (DOI: 10.1002/polb.23213), and the fast switching of all-printed organic electrochemical transistor (DOI: 10.1016/j.orgel.2013.02.027). These journal articles can be found through the title "Publications" in the right sidebar.

The possibility to integrate these devices results in a unique all-printed biosensor concept presenting a new paradigm in inexpensive biosensing devices. The integrated biosensor shown below is an entire system including power source, sensor and display all printed on a sheet of flexible plastic or paper. Circuitries to drive the electronics was made on a printed circuit board but is in later prototypes replaced with a chip. The sensor used today in the integrated demonstrator is a glucose sensor to demonstrate the possibilities of the platform. The concept can be utilized for other sensor analytes and mechanisms, including enzymatic (biological recognition and detection) or affinity with microfluidics, provided there is an electrochemical transduction mechanism.  The platform is versatile and adaptable to specific user needs and applications, including adding communication technology.  A video that shows the functionality of the sensor platform can be found by clicking the picture to the right. This was as well featured in an article in Chemical Society Review by Anthony Turner head of Biosensors and Bioelectronics Centre at Linköping University, DOI: 10.1039/C3CS35528D.
