The biosensor, a collaborative development by the University of Florida and National Yang Ming Chiao Tung University in Taiwan, employs paper test strips coated with specific antibodies. These antibodies interact with cancer biomarkers targeted in the test. Upon placing a drop of saliva on the strip, electrical pulses are sent to contact points on the biosensor device. This process leads to the binding of biomarkers to antibodies, resulting in a measurable change in the output signal. This change is then converted into digital data, indicating the biomarker’s presence. It tests for biomarkers in the saliva. Possibly not outright crazy charlatan territory. Could certainly use a larger sample size though, especially given that one of its bragging points is "fast and cheap!"
