FLUCTUATION-ENHANCED CHEMICAL/BIOLOGICAL SENSING AND PROMPT IDENTIFICATION OF BACTERIA BY SENSING OF PHAGE-TRIGGERED ION CASCADE (SEPTIC)

摘要

Both selectivity and sensitivity of chemical sensors can be significantly improved by exploiting the information contained in micro-fluctuations present in the sensor system. We call our collection of methods to extract information from these micro-fluctuations Fluctuation-Enhanced Sensing (FES). In this review paper we discuss general FES principles and two types of applications; gas sensing with commercial solid state sensors and the Sensing of Phage-Triggered Ion Cascde (SEPTIC) technique to detect and identify bacteria.
