Medical diagnosis relies on the detection of biologically-active molecules via devices that often require bioactive surfaces. Biotechnology, the science of elucidating, and modifying & producing bioactive molecules, contributes to many clinical diagnostics such as:
- Preparation of engineered surfaces for the identification of DNA through hybridization to large arrays of diverse DNA molecules produced by spatially-directed synthesis
- Preparation of analytical devices by antibody immobilization and subsequent chemical detection
- Purification and identification of cell sub-populations by interactions between their receptors and specially engineered substrates
