- Biosensors
- use biological components to determine the presence and concentrations of molecules such as glucose
- Analyte = the compound under investigation
- 1. Molecular Recognition
- a protein (enzyme or antibody) or single strand of DNA (ssDNA) is immobilised to a surface
- This will interact with or bind to the specific molecule under investigation
- 2. Transduction
- the interaction will cause a change in the transducer
- Transducer- detects changes e.g. in the pH and produces a response
- 3. Display
- produces a visible, qualitative or quantitative signal
- such as a particular colour on a test ***** or reading on a test machine
