Priscilla Kosaka, 35, a researcher at the Institute of Microelectronics of Madrid six years ago, developed a less invasive method that uses a nano-sensor that is “ten million times more effective” than traditional tests performed on blood samples of patients.
The sensor with antibodies on the surface, is like a “very tiny trampoline” and when in contact with a person’s blood sample with cancer “catch” the different particle and is heavier, explained the researcher, quoted by news portal G1.
Other components associated with the technique also mean that there is a change in color of the cells, indicating the presence of a malignant tumor.
“Currently there is no technique that allows the detection of molecules that are at very low concentrations and to coexist with more than 10 thousand species of proteins in a single bio-sample,” he said, stressing that, today, no method allows to find “needle in palheiro`”.
“So there is a need for technologies that can record individual molecules in the presence of other molecules much more abundant and nano-sensor developed is able to do this,” he stressed in remarks quoted by the G1.
According to the scientist, further studies can cause the nano-sensor can be improved in order to identify the type of cancer cells detected in the sample (gastrointestinal or pancreatic cancer for example).
World Health Organization data (WHO) indicate that each year are detected worldwide 21.4 million cases of cancer.
