IBM has Silicon Chip Tests for Disease in Rapid Time, Using Microscopic Sample


IBM scientists have created a one-step point-of-care-diagnostic test, based on an innovative silicon chip, that requires less sample volume, is significantly faster, portable, easy to use, and can test for many diseases, including one of world's leading causes of death, cardiovascular disease. The results are so quick and accurate that a small sample of a patient’s serum or blood, could be tested immediately following a heart attack, to enable the doctor to quickly take a course of action to help the patient survive.



IBM Research - Zurich scientists Luc Gervais and Emmanuel Delamarche, in collaboration with the University Hospital of Basel in Switzerland, have developed a new diagnostic test that uses capillary forces to analyze tiny samples of serum, or blood, for the presence of disease markers, which are typically proteins that can be detected in people’s blood for diagnostic purposes. Capillary action force is the tendency of a liquid to rise in narrow tubes or to be drawn into small openings. An everyday example of a capillary action force can be viewed by dipping a paper towel in a cup of water — the microstructures in the paper fiber enable the towel to absorb the water.
