Large analytes targeted by affinity biosensor technology include bacterial pathogens such as Escherichia coli, Salmonella enteritidis, and Listeria monocytogenes. Salmonella enteritidis and Listeria monocytogenes were detected by an SPR sensor at concentrations down to 106 cfu/ml27. 

Future development of affinity biosensors based on spectroscopy of guided waves will be driven by the needs of the consumer. These biosensor technologies hold potential to benefit important fields including pharmaceutical research, medical diagnostics, environmental monitoring, food safety, and security. Applications in these areas will challenge research and development in the field.

In order to conceptually analyze the main components and functionality of a multibiosensor technological platform that could be used as an early warning system for biological and/or chemical warfare, we will review three different optical biosensor technologies ... 

Electrochemical impedance measurements of the physical adsorption of ssDNA and dsDNA yields useful information about the kinetics and mobihty of the adsorption process. Physical adsorption of DNA is a simple and inexpensive method of immobilization. The ability to detect differences between ssDNA and dsDNA by impedance could be applicable to DNA biosensor technology. EIS measurements were made of the electrical double layer of a hanging drop mercury electrode for both ssDNA and dsDNA [34]. The impedance profiles were modeled by the Debye equivalent circuit for the adsorption and desorption of both ssDNA and dsDNA. Desorption of denatured ssDNA demonstrated greater dielectric loss than desorption of dsDNA. The greater flexibility of the ssDNA compared to dsDNA was proposed to account for this difference.
