As per reports, it has been revealed that a group of researchers from the Princeton has improved the sensitivity of immunoassays, a medical test to assess a host of diseases. The study researchers were of the view that they have increased the sensitivity of the test by more than 3 million times.

In order to do that they used standard biological tools with the combination of nanotechnology. Lead researcher Stephen Chou, of the Joseph C. Elgin Professor of Engineering, was of the view that the increased sensitivity of the test will help doctors to check diseases like Alzheimer's disease and cancer, more accurately.

The test uses the action of the immune system, so that it can detect the presence of biomarkers, which will be indicated in fluorescent color. Chou said that the greatest the glow, more the biomarker is present in the blood.

Chou said that they will be conducting a further research in order to increase the detection limit. "This advance opens many new and exciting opportunities for immunoassays and other detectors, as well as in disease early detection and treatment”, said Chou.

The study was being funded by the two institutions, the Defense Advanced Research Project Agency and the National Science Foundation.
