Liposome immunosensor for theophylline
Biochemical and Biophysical Research Communications, 1980Abstract A new simple, sensitive liposome immunosensor (LIS) has been developed by combining the advantages of spin membrane immunoassay (SMIA) and enzyme immunosensor (EIS). The LIS system is composed of an oxygen electrode and sensitized liposomes.

Immunosensors in clinical analysis
Fresenius' Journal of Analytical Chemistry, 2000Clinical analysis requires methods of high reliability. The importance of immunosensors in clinical analysis is discussed. Due to the fact that the construction of immunosensors plays a very important role in their response characteristics, different types of immunosensor designs are highlighted.

Microfluidic immunosensor systems
Biosensors and Bioelectronics, 2005Immunosensing microfluidic devices are reviewed. Devices are commonly fabricated in glass, silicon, and polymers, with polymers seeing greater attention in recent years. Methods have been developed to immobilize antibodies and other molecules and resist non-specific adsorption through surface modification.

Journal of Solid-Phase Biochemistry, 1979
An immuno responsive membrane was prepared by immobilizing Wasserman antigen to acetylcellulose. The antigen-binding membrane was used in developing an immunosensor for determining specifically corresponding antibody in serum. The senor is characterized by electrochemical determination of the antigen-antibody complex formed at the membranesoluti on ...

Immunosensors for clinical diagnostics
1997Enzmye immunoassays couple the amplification produced by enzymatic reactions to the sensitivity of the immune reaction. The growing trend away from radioimmunoassay, and the increasing number of enzyme-linked immunoassays, coupled with the wide range and low detection limits of the electroanalytical methods, has resulted in a proliferation of papers ...

Advances in electrochemical immunosensors
2019Immunosensors are compact tools on which antibody and antigen interactions are formed. The specific interaction between antibody and antigen is detected by using a transducer and an electrical signal is measured. This specific interaction between these molecules makes immunosensor very attractive for several applications in different fields ...

Towards amperometric immunosensor devices
Biosensors and Bioelectronics, 1997In contrast to optical immunosensors, the electrochemical detection of an immunanalytical reaction does require a labeling, but allows an easier discrimination of specific and non-specific binding. We present a concept and first results for a multivalent amperometric immunosensor system which is based on silicon technology.

Microbiosensors and Immunosensors
1990Chemical reactions in organisms proceed smoothly because of the action of catalysts such as enzymes. These are highly specific for chemical substances with which they form complexes to promote their reactions. By using enzymatic analyses, therefore, many substances may be measured.
