The special sensor is based on a
newly emerging technique of combining electronic sensors with biomolecular
recognizers, enzymes, antibodies, even living cells. For example, the heart
infarction bio-sensor is made possible by the recent discovery of a new marker,
a fatty acid-binding protein, that appears in the blood within one to two hours
after the onset of the chest pains that are the first symptoms of heart
infarction. By employing this recent advance the heart biosensor could be
engineered to be accurate, quick, and cheap. |
