Dear readers, Prof. Chen and Prof. Ju did a hard job as guest editors in order to organize this special issue concerning selected papers from the 2nd International Symposium on Sensor Sciences (I3S 2004). Four further articles have been already published as regular papers in Sensors within the last months:
- -
- Integration of a Capacitive EIS Sensor into a FIA system for pH and Penicillin Determination, Sensors, 2004, 4, 84.
- -
- Inorganic Thin-Film Sensor Membranes with PLD-Prepared Chalcogenide Glasses: Challenges and Implementation, Sensors, 2004, 4, 156.
- -
- Fabrication of Thin-Film LAPS with Amorphous Silicon, Sensors, 2004, 4, 163.
- -
- “Playing around” with field-effect sensors on the basis of EIS structures, LAPS and ISFETs, Sensors, 2005, 5, 126.
I would like to take the opportunity to thank Prof. Chen and Prof. Ju for their contribution to Sensors.
