Analytical biosensors for the pathogenic microorganisms determination

Abstract

Detection and quantification of microbial pathogens are usually the first procedure before the application of any strategy for combating them. In the last years, analytical biosensors provide a promising alternative for direct pathogenic microorganisms determination. These sensors are analytical devices composed of a recognition element of biological origin and a physico-chemical transducer. Biosensors technology in general seeks to improve analytical performance by reducing the consumption of reagents, decreasing the analysis time, increasing reliability and sensitivity through automation, and integrating multiple processes in a single device. The present chapter focuses applications of analytical biosensors to microbiological diagnostics in areas such as diagnosis of diseases and food quality control including fabrication techniques as well as future perspectives.
