A team of scientists at the University of Queensland (Australia) has developed a method that can detect different types of cancer in a person's bloodstream in just 10 minutes, according to a study published this week in Nature Communications. .
The method consists of a liquid which contains gold nanoparticles, to which the DNA of the malignant and healthy cells adheres, but the coloration taken by the solution is different in both cases. The gold nanoparticles gave a pink shade to the solution used in the research. By adding healthy human tissue samples, the liquid takes on a blue color, but in the presence of cancer cells the solution retains its pink hue.
This technique proved to have an accuracy of up to 90% in tests with 200 samples of breast, prostate or colorectal cancer, as well as in lymphoma, conducted by researchers at the University of Queensland.
"Surely we still do not know whether it is the holy grail for all cancer diagnoses, but it looks really interesting as an incredibly simple universal arc for cancer, and as an affordable and affordable technology that does not require complex laboratory equipment, "said Professor Matt Trau, who led the study.
"One of the main advantages of this technique is that it is very cheap and extremely simple to do so that it could be adopted at the clinic quite easily, "said Laura Carrascosa, co-author of the paper, quoted by The Guardian newspaper.
However, Carrascosa points out that doctors will have to perform additional and more specific analyzes for their patients. "Our technique could be a detection tool to inform doctors that a patient may have cancer, but would require further testing with other methods to identify the type and stage of cancer"explained Carrascosa.
