[Biosensors in the pharmaceutical domain].
Biosensors are analytical devices which incorporate a biological component (enzyme, antibody, animal or plant cell, DNA fragments, lipids.) intimately connected to a physical transducer (electrode, optical fibre, vibrating quartz.). This dual configuration allows the study of a great variety of compounds of pharmaceutical interest which react with the biocomponent. The latter is selected depending on the application and the performance criteria requested. Biosensors are suitable for real time monitoring such as in bioreactors, and for the determination of various physiological and pharmacological parameters. Biosensors may be employed in home testing (glucose, lactate.), in hospitals (bedside testing, emergency, surgery, dialysis monitoring, etc.) in clinical laboratory analyses (immunoassays, DNA analysis.) and at research centres. Ideally, a biosensor should be easy to use, allowing direct analysis without sample pre-treatment. Measurements should be automatized and remote controlled. The biosensor may be miniaturized for single use or for implementation in sensor arrays. Applications to microenvironments (in vivo, single cell.) or discrete one shot decentralized tests may also considered.
