(Professor, Aachen University of Applied Sciences, Jülich Campus) 「Transistors – „tracking dogs” for ions and biomolecules」 ‘Biology meets microelectronics’ – a phrase oft quoted in recent times, and one which underlines the increasing importance of inter- and trans-disciplinary research activities. Basic scientific disciplines such as physics, electrical engineering, chemistry, biology and materials science are increasingly seen to overlap common boundaries, so defining the interface of an exciting research environment with a high potential for innovation. In this context, the INB (Institute of Nano and Biotechnologies) at the Aachen University of Applied Sciences aims to combine synergistically its existing expertise in the fields of semiconductor technologies, nano-electronics, silicon-based chemical sensors and biosensors along with biotechnology (plant and microbiology/bioprocess technology and mammalian cell cultures). Four research laboratories will focus their research activities on the pioneering spectrum of nano- and biotechnologies, a broad contemporary research area, fostering new ideas and the design of new products which may change our daily life. Penicillin detection in bioreactors, determination of garlic in herbal drugs, heavy metals, pesticides and highly toxic cyanide in waste water, or DNA analysis are representing some examples how to combine chip technology with highly sensitive and selective (bio-)chemical recognition elements. Among the multitude of concepts discussed in literature, semiconductor-type field-effect devices, such as the capacitive EIS (electrolyte-insulator- semiconductor) sensor, the LAPS (light-addressable potentiometric sensor) and the ISFET (ion-sensitive field-effect transistor, belong to the most attractive approaches. These three kinds of devices are currently being the basic structural element in a new generation of chemical and biological microsensors, fabricated by means of silicon planar technology. Moreover, these devices provide advantages over conventional approaches such as the small size and weight, the fast response time, the possibility of an on-chip integration of sensor arrays, the high robustness, the possibility of low-cost fabrication, etc. At the same time, their possible field of application reaches from medicine, biotechnology, process control and environmental monitoring through food and drug industries up to defence and security requirements. |
