Biosensors are used to detect and quantify biological material associated with a disease state or health condition (biomarkers). Biosensors are therefore powerful tools for diagnosis and monitoring. As technological advances allow for such tests to be conducted faster and on smaller devices, these tests are moving out of specialised laboratories and closer to the patient at the point-of-care. This report gives a complete analysis of the important trends in the field of medical biosensors, and lists the new technologies and devices which are likely to be highly disruptive to the in vitro diagnostics market.
