Detecting a cancer does require a very sophisticated medical device. But more recently in a study published in Angewandte Chemie, the researchers point out that an imaging technique called scanning electrochemical microscopy could be a very useful medical tool for detecting cancer in human tissues.
Instead of using additional chemicals such as dyes or fluorescent markers to see the tissue well, this method uses an electrochemical probe to detect natural biomolecules around human tissues.
In this study, the researchers used soft microelectrons that were gently brushed across tissue samples. When there is movement, the researchers measure the electrical current generated by certain chemicals in the tissues to get an idea of the physical structure of the tissue as well as its composition.
Not to be missed, the research team also gave three separate demonstrations of the use of this new technique. In the initial study, they used rat liver as a research material to show that certain types of nanoribbonthat studied as potential drug delivery mechanisms could be distributed throughout the liver.
As for the second demonstration, the probe measures the hemoglobin protein to get a full picture of the rat heart that you can see in the picture above. For the last experiment, they used this technique to show that it can accurately distinguish healthy human tissue from cancer tissue.
In the future, researchers not only want to use this method to detect cancer cells, but they also want to destroy the cells. But there are still obstacles in doing so, where to destroy cancer cells on a thick network is still difficult to do.
