The research in medicine is always working on identifying weapons to activate against the cancer cells. A positive result, which brings hope for the future in the oncology field. We are talking about an advanced technology, intelligent nanotechnologies created with the filaments of the DNAwhich when intertwined are similar to origami, if activated in the right way can intercept tumor cells to lead them to self-destruction. They work like the immune system, these nanorobot They navigate the human body and when the conditions become ideal they recognize tumor cells and attack them.
The researchers state that this process occurs in the acidic microenvironment which presents a ph around the levels of 6.5. Under these conditions, the nanorobot killer recognize tumor cells, attacking them and leading to their elimination. If, on the other hand, the microenvironment remains stable at around 7.5 pH, everything proceeds normally. An indispensable circumstance, because when there are cancer cells inside the human body, an acidic environment is created around them. This is why those responsible for the research have shown themselves enthusiastic about the results of the same, even if they will have to test it on humans.
Björn Högberg is a professor at the Department of the Institute at Karolinska Institutet, who said that they have succeeded in creating a nanorobot that kills tumor cells. At the moment, tests have been performed on animals with tumors closely related to breast cancer. The real challenge will be to verify whether it will be possible to act on humans with human diseases and whether the outcomes can be positive, without presenting contraindications for healthy cells.
Hope for future treatments
This research represents an important step forward in the field of effective therapies against cancerhowever, this is an experiment, it is not a currently applicable therapy. Yang Wang, the researcher responsible for the research at the Department of Medical Biochemistry and Biophysics at Karolinska Institutet, said that they will have to check whether this technique can be applied to human tumor diseases.
I nanorobot represent an important step in cancer research, but the same researchers have stated that it is necessary to explore the sector to improve the action capabilities of nanorobots. To do so, they will focus on a technique, trying to fix some proteins on the surface, which tend to bind to some types of cancer. The road to the future is still in experimentation, but hope seems closer in finding a cure for cancer.
