Magnetic transducers in biosensors and bioassays

Abstract

In affinity biosensor technology, antibodies are employed as the recognition element in close conjunction with a transducer. Much work has been put into developing effective transducers, and a number of technologies exist. In this review various works that we have found significant to the field of magnetic transducers in bioanalysis have been critically studied in order to describe the status and development of magnetic measurements in biosensors and bioassays. Our group has previously suggested that magnetic transducers in combination with magnetically labelled antibodies may be used in this context and this so-called magneto immunoassay (MIA) technique will be dealt with in some detail.
