On Wednesday (December 27), Science Alert reported that scientists from Rice University, Texas A&M University, and the University of Texas (USA) have successfully tested a new method that can kill up to 99% of cancer cells by using synchronized vibrations to break down cancer cell membranes.

Specifically, this method uses near-infrared light to stimulate aminocyanine molecules—a fluorescent dye commonly used in medicine—causing the electrons within them to vibrate in unison (plasmon oscillations), enough to break down cancer cell membranes.
According to the study, each plasmon will have an "arm" on one side, helping to connect the molecules to the cancer cell membrane. Therefore, when vibrations appear, they will be separated from each other.
As a result, 99% of the human malignant tumor cells cultured in the laboratory were destroyed. The research team said this new method marks a significant improvement over other previously developed cancer-killing methods.
Although it is only the initial stage, this method offers great hope for patients with cancer in organs that are difficult to treat completely, such as bone cancer.
"This is the first time a molecular plasmon has been used in this way to excite an entire molecule and create a mechanical impact that is specific to a target, in this case tearing apart a cancer cell membrane," said team member Ceceron Ayala-Orozco, a chemist at Rice University.
According to a study published in Nature Chemistry, this is a simple yet effective biomechanical technique that makes it difficult for cancer cells to develop resistance to treatment. Researchers are exploring other molecules with similar potential applications and moving towards more advanced testing, including animal testing and clinical trials.
