A team of scientists from the University of Queensland (Australia) has developed a method that can detect different types of cancer in the bloodstream of a person in just 10 minutes, according to a study published this week in the Journal of Nature Communication.
The method consists of a liquid that Contains gold nanoparticles, To which the DNA of the malignant and healthy cells adheres, but the elimination of the solution is different in both cases. The gold nanoparticles gave a pink hue to the solution used in the investigation. When adding samples of healthy human tissues, the fluid takes a blue color, but in the presence of cancer cells, the solution maintains its pink hue.
This technique has proven to have An accuracy of up to 90% In tests with 200 samples of breast, prostate or colorectal cancer, and also in lymphoma, conducted by researcher at the University of Queensland.
"Certainly we still do not know if it is the holy grill For all cancer diagnoses, But it seems 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, it can be easily accepted in the clinic, "said Laura Carrasco, co-author of the work, quoted by the Geyan newspaper.
However, carrascosa shows that doctors will have to perform even more specifically to their patients. "Our technique could be A Detection tool To inform doctors that a patient could have cancer, but would require further testing with other methods Identify the type and stage of cancer"Clarified Carrascosa.
