A team of scientists from the University of Queensland (Australia) has developed a methodology that can detect different types of cancer in a person's bloodstream in just 10 minutes, according to a study published in Nature Communications this week. .
The method consists of a liquid Contains gold nanoparticlesThe malignant and healthy cells adhere to the DNA, but the coloration taken by the solution is different in both cases. Gold nanoparticles gave a pink color to the solution used in the investigation. When adding samples of healthy human tissue, the liquid gets a blue color, but preserves the pink tone of the solution in the presence of cancer cells.
This technique has been proven to have. Accuracy up to 90% Tests carried out by researchers at the University of Queensland, chest, prostate or colorectal cancer as well as tests with 200 samples of lymphoma.
"Of course, we don't know if there is a sacred bowl. for all cancer diagnosesHowever, Professor Matt Trau, who led this work, seems really interesting as an affordable and affordable technology that does not require an incredibly simple universal spring for cancer and no complicated laboratory equipment.
"One of the most important advantages of this technique, very cheap and extremely simple Doing so can be easily accepted in the clinic, "said The Guardian newspaper co-author Laura Carrascosa of the study.
However, he points out that doctors will have to do additional, more specific analyzes to their patients. "Our technique may be a detection tool The doctor should inform the patient that he may have cancer, but require further testing in other ways Describe the type and stage of cancer."clarified Carrascosa.
