IMB-CNM talks: Inkjet-printed devices for chemo-/biosensing applications

Abstract: Inkjet printing is a nascent technology that is evolving from text and graphic printing into a major topic of scientific research and R&D, where it can be used as a highly reproducible non-contact patterning technique to deposit liquid functional materials at high speed on either small or large areas of flexible and non-flexile substrates. It is a low cost technique because minimizes the waste products and reduces the process steps. The development of organic materials such as polymers with electrical features has boosted the fabrication of new organic printed electrical devices.
In this framework, the talk is devoted to the development of two novel organic devices for chemo-biosensing applications for a low-cost cost devices using inkjet printing technology. The first sensor is an inkjet-printed Metal-Insulator-Semiconductor (MIS) diode. Its simple fabrication process of these diodes also makes it advantageous for scaling up to roll-to-roll production. Moreover, it has been shown that the MIS diode shows a good selectivity to detect NO2. The second sensor is based on Biological Field-Effect Transistor (BioFET). This device was fabricated and optimized to operate correctly under aqueous media and to detect biomolecules.
