Finding diseases like cancer in an organism only through a blood test is like looking for a needle in a haystack, since the concentration of molecules that allow the detection of the disease is very low. However, this scenario can change in up to 10 years, thanks to the invention of a Brazilian scientist.
Priscila Monteiro Kosaka, 35, has spent the last six years poring over research at the Institute of Microelectronics in Madrid, Spain, and has succeeded in creating a revolutionary sensor that can identify diseases such as cancer, hepatitis and even alzheimer's.
The nanosensor has a sensitivity about 10 million times greater than any other existing method and requires only a single blood test from the patient - a breakthrough against biopsies and invasive exams that until then were the only method available to identify diseases like these.
Acting as a kind of springboard, the sensor carries antibodies on its surface and gets heavier by picking up disease-related particles. The device also causes a change in the coloration of the particles, facilitating identification.
The error rate, according to the scientist, is 2 in 10,000 cases. The discovery is still in the final stages of testing, but the goal is for the sensor to be routinely used within 10 years.
