Bio-layer interferometry (BLI) is an optical biosensing technology that analyzes biomolecular interactions in real-time without the need for fluorescent labeling. [1] Alongside Surface Plasmon Resonance , BLI is one of few widely available label-free biosensing technologies, a detection style that yields more information in less time than ...
Bio-FETs couple a transistor device with a bio-sensitive layer that can specifically detect bio-molecules such as nucleic acids and proteins. A Bio-FET system consists of a semiconducting field-effect transistor that acts as a transducer separated by an insulator layer (e.g. SiO 2) from the biological recognition element (e.g. receptors or probe molecules) which are selective to the target ...
Bioinstrumentation has been incorporated into novel diagnostic tools that are utilized for a variety of patients. There is a sufficient challenge to implementing real-time measurement systems that are lightweight, comfortable and efficient, so there has been increased drive for the novel development of more flexible and compact bioinstrumentation.
Biacore was founded in 1984 under the name of Pharmacia Biosensor AB, by researchers from Pharmacia, Linköping Institute of Technology and the Swedish National Defence Research Institute (FOA, now renamed the Swedish Defence Research Agency or FOI). The first Biacore SPR instrument was commercially released in 1990.
Biosensors used for screening combinatorial DNA libraries. In a biosensor, the bioreceptor is designed to interact with the specific analyte of interest to produce an effect measurable by the transducer. High selectivity for the analyte among a matrix of other chemical or biological components is a key requirement of the bioreceptor.
Biosensors based on type of biotransducers. A biotransducer is the recognition-transduction component of a biosensor system. It consists of two intimately coupled parts; a bio-recognition layer and a physicochemical transducer, which acting together converts a biochemical signal to an electronic or optical signal.
However, this model remains a long-term goal, and research is currently focused on the immediate diagnostic capabilities of nanosensors. The intracellular implementation of nanosensor synthesized with biodegradable polymers induces signals that enable real-time monitoring and thus paves way for advancement in drug delivery and treatment.

As SPR allows real-time monitoring, individual steps in sequential binding events can be thoroughly assessed when investigating the suitability between antibodies in a sandwich configuration. Additionally, it allows the mapping of epitopes as antibodies of overlapping epitopes will be associated with an attenuated signal compared to those ...
