Australian scientists have developed a new test capable of detecting cancer in just 10 minutes, using DNA obtained from a blood sample.
Early detection has significantly improved the prognosis of cancer. Scientists around the world have been trying to find new ways to identify the disease as soon as possible.
This was decided by a team of Australian scientists from the University of Queensland who recently created an experimental test capable of detecting this disease in just 10 minutes. This was possible since scientists have come to the conclusion that cancer forms a unique DNA structure when it is placed in water .
In the study published this Tuesday in Nature Communications . Matt Trau explains that "it is obvious that molecules are the molecules of molecules and that molecules the cancerous DNA formed of 3D nanostructures completely different from the circulating DNA. is a breakthrough that has allowed an entirely new approach to the non-invasive detection of cancer in any tissue type, including blood. "
It is from this discovery that the team created portable detection devices that can be adapted to smartphones in the future.
At this stage of the investigation, however, for the moment, its application to more than 200 blood and human tissue samples has detected cancer cells with a 90% . At this point, according to Vision, the test has been applied to bad, prostate, intestinal and lymphoma cancers
It is true that cancer alters the DNA of healthy cells, but different types of cancer have different signatures. Thus, scientists point out the difficulty of finding a common trait that distinguishes healthy cells from those affected by cancer.
However, "this unique DNA signature appeared in all types of bad cancer that we examined and other forms of cancer, including prostate, colorectal and lymphoma", said Abu Sina, another researcher at the University of Queensland.
"We designed a simple test using gold nanoparticles to instantly change color to determine whether 3D nanostructures of cancerous DNA are present," said Trau.
According to the team, these gold particles bind to the affected DNA and changes in molecular behavior that cause a color change. can be observed with a high resolution microscope.
"Certainly we do not know yet about the Holy Grail of all cancer diagnoses, but that sounds really interesting." Read the statement.
