Cancer specialists have been conducting extensive research for many years in search of effective treatment methods. Now, researchers have explored the use of nanorobots as a weapon to eliminate cancer cells.
Recently, researchers at the Karolinska Institute developed a nanorobot, that can destroy mouse cancer cells. Details about this breakthrough were published in Nature’s ‘Nanotechnology’ journal. In the journal, it is noted that the robot is designed in a tiny form that allows it to enter tumors, release its contents, and preserve healthy cells.
Previously, a team of researchers at the Karolinska Institute had created a hexagonal peptide structure using a chain of amino acids. They claimed this structure could attach to the cell wall and activate the "death receptor" process. However, a significant issue arose when they observed that, upon entering a cancer-affected body, this peptide structure could begin killing the body’s healthy cells. This can lead to harmful side effects.
To address this, scientists have now hidden the robot within a nanoscale structure made of DNA. This allows it to act only within the tumor environment and effectively target cancer cells. Researchers report that this treatment has no side effects.
Currently, this nanorobot has been tested on mice. Observations indicate that the active nanorobot was able to reduce tumor growth by up to 70% in mice.
In this regard, Yong Wang, a researcher in the Department of Medical Biochemistry and Biophysics at the Karolinska Institute, told the media that this method will be applied to more complex cancer models. Further rigorous testing on various types of complex tumors is still required.
