Biochips to diagnose diseases in tissue or blood samples may largely replace test-tubes. The entire lab can be conducted on the chip, called lab-on-a-chip, rather than add external tubing to detecting or measuring devices.[1]

Researchers are developing a way to test glucose levels of saliva, as a way of replacing blood tests to measure glucose.[2]

Diagnoses can be made more quickly and more accurately with biochips. Cancers can be detected through biochips before symptoms occur.[3]

Learning Task[edit]

International Space Station - Medical Experiments - Lab-on-a-Chip
  • Explore the benefits and challenges of a Lab-on-a-chip application?
  • On the International Space Station Lab-on-a-chip experiments can be performed. It is small group of astronauts that maintain a huge number of experiments in a limited time span and under resource constrainted conditions. Compare the Lab-on-a-chip application in a terrestial and outer space environment!
  • Compare Lab-on-a-chip application in medical environment with Lab-on-a-chip application e.g. environmental sciences!
