Scientists develop ‘nano-nose “that can detect cancer early




A group of scientists said to be able to detect by means of a nano device that detects specific substances in the body. Developing tumors at a very early stage The small size ensures that the patient does not necessarily need to go to the hospital for the test.

It is a nano device that is inlaid with gold atoms on fibers of 4 microns long, where a micron is one thousandth of a millimeter. Furthermore, use is made of antibodies, molecules that bind to a specific substance, and can be used for detection. Thereby deployed In total, the device diameter of only 125 microns.

By looking at vibrations of electrons in the material, something that is localized surface plasmon resonance is known, the presence of a certain substance can be demonstrated. According to the scientists, their technology is significantly more sensitive than existing detection techniques. Due to the presence of certain substances, such as those belonging to the immune system or cancer-specific molecules, demonstrating early to a treatment may be started, so that the probability of success is greater earlier.

Another advantage of the so-called nano-nose is that the whole can be in a small housing packaged. This ensures that patients do not necessarily come to take off the test to the hospital; The doctor can also take the device to the patient. However, it is still unclear how such a test will cost.

In the lab, scientists have worked at the University of Alabama in Huntsville, demonstrated that they can prove. presence of PSA in small concentrations This fabric is widely used in the diagnosis of prostate cancer. If desired, the assay can be adapted to detect other important biomarkers according to the scientists.

The researchers will have to demonstrate that their nano-nose also works with patients; this they hope to be able to raise money. It would seem to be unlikely that all cancers can be detected early. There are, in most cases, no biomarkers available which can already provide information about the presence of developing tumors. Answer at an early stage
