Priscilla Kosaka, 35, a researcher at the Institute of Microelectronics of Madrid six years ago, developed a less invasive method for detecting cancer cells using a nano-sensor – “ten million times more effective” than traditional tests performed on blood samples of patients.
The sensor with antibodies on the surface, is as a “springboard very tiny” and when in contact with a person’s blood sample with cancer “catch” the different particle and is heavier, explained the researcher, quoted by the Brazilian 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.
“There is currently no technique which allows 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, “said Priscilla Kosaka, stressing that currently no method allows to find the” needle in a haystack. “
“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 said.
According to 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).
