Detection of bacterial signaling molecules in liquid or gaseous environments.

The detection of bacterial signaling molecules in liquid or gaseous environments has been occurring in nature for billions of years. More recently, man-made materials and systems has also allowed for the detection of small molecules in liquid or gaseous environments. This chapter will outline some examples of these man-made detection systems by detailing several acoustic-wave sensor systems applicable to quorum sensing.

Analogies between digital radio and chemical orthogonality as a method for enhanced analysis of molecular recognition events.

Acoustic wave biosensors are a real-time, label-free biosensor technology, which have been exploited for the detection of proteins and cells. One of the conventional biosensor approaches involves the immobilization of a monolayer of antibodies onto the surface of the acoustic wave device for the detection of a specific analyte. The method described within includes at least two immobilizations of two different antibodies onto the surfaces of two separate acoustic wave devices for the detection of several analogous analytes.
