IBM scientists have created a one-step point-of-care-diagnostic test based on an innovative silicon chip that is easy to use and can test for many diseases, including 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 and to predict the patient's survival rate.
IBM scientists have encoded the forces of capillary action on a microfluidic chip made of a silicon compound, similar to those used in computer chips, thus leveraging IBM's vast experience in developing and manufacturing silicon semiconductor wafers. The chip, which measures 1 × 5 centimeters, contains sets of micrometer wide channels where the test sample flows through in approximately 15 seconds, several times faster then traditional tests. Uniquely, the filling speed can be adjusted to several minutes when the chip requires additional time to read a more complex disease marker.
