**About the Editors**

**Tatsuo Yoshinobu** (Ph.D.) was born in Kyoto, Japan in 1964. He received his BE, ME, and PhD degrees in electrical engineering from Kyoto University in 1987, 1989, and 1992, respectively, where he studied gas source molecular beam epitaxy of silicon carbide. In 1992, he joined the Institute of Scientific and Industrial Research, Osaka University, where he started the development of silicon-based chemical sensors. From 1999 to 2000, he was a guest scientist at the Research Centre Julich, Germany. Since 2005, he has been a professor of electronic engineering at Tohoku University, ¨ Sendai, Japan. Since 2008, he has also been a professor at the Graduate School of Biomedical Engineering, Tohoku University.

**Michael J. Sch ¨oning** (Ph.D.) received his diploma degree in electrical engineering (1989) and his PhD degree in the field of semiconductor-based microsensors for the detection of ions in liquids (1993), both from Karlsruhe University of Technology. In 1989, he joined the Institute of Radiochemistry at Research Centre Karlsruhe. Since 1993, he has been with the Institute of Thin Films and Interfaces at the Research Centre Julich (now, Institute of Biological Information Processing) ¨ and in 1999 was appointed as a full professor at Aachen University of Applied Sciences, Campus Julich. Since 2006, he has served as the director of the Institute of Nano- and Biotechnologies ¨ (INB) at Aachen University of Applied Sciences. His main research subjects concern silicon-based chemical and biological sensors, thin-film technologies, solid-state physics, microsystem, and nano(bio-)technology.
