Universal cancer test in under 10 min in development
Researchers at the University of Queensland have developed a simple, inexpensive way to diagnose cancer that takes less than 10 minutes, is versatile, and can determine the presence of a disease with 90% accuracy..
Scientists have made a breakthrough with the discovery that the DNA of healthy and cancer cells interacts differently with the surface of metals and reacts to water. The essence of the new rapid test is that suspicious DNA put in water with gold nanoparticles and observe the change.
After adding tiny particles of precious metal to the liquid, it turns pink. Introduced DNA mutated cells it just sticks to the gold, so the water stays pink and healthy genetic material reacts, causing the solution to turn blue.
Scientists have tested the new technique on 200 samples of cells with different types of cancer, and in 90% of cases the ten-minute test results were correct. At the moment, the technology allows only to establish the presence of a disease, but does not provide information about its type or location. Therefore, such an analysis can only be used as an initial tool if the doctor has suspicions, and if confirmed, further diagnostics will be required..
The development team says the test is still under development as further trials are required to assess its full clinical potential..
Combined with other simple analyzes, it can be a powerful diagnostic tool.
In perspective the new rapid test can be included in the complete blood count.
Invasive methods of analysis will soon change dramatically. This will be facilitated by inventions such as the new nanotweezers created by chemists at Imperial College London that allows you to biopsy a cell without destroying it.
