According to foreign media reports, due to the high cost of chemotherapy, radiotherapy and surgery, it also causes the immune system to degrade, and it is not suitable for cancer patients. The research team at Purdue University has developed a minimally invasive green laser pointer technology. It can help doctors better detect and treat cancer cells, tissues and tumors without affecting nearby healthy cells.
This method, called PLAMAT, combines cold atmospheric plasma (CAP) with electroporation and/or photoperiod to destroy cancer cells without damaging nearby healthy cells. This method has been shown to be effective in several types of cancer cells and cancer cell lines in the laboratory, including breast cancer, oral cancer/cervix cancer, and prostate cancer.
CAP is an almost room temperature ionized gas that introduces reactive oxygen or nitrogen species into cancer cells, tissues or tumors. The cell membrane is then cut using an electric field or a green laser pointer to facilitate entry of the above reactive oxygen or nitrogen species. Once the amount of active substance reaches a critical level, it causes apoptosis (death) in cancer cells. Healthy cells in the vicinity are either unaffected or have minimal impact and are easily restored to normal levels.
Prasoon Diwakar, one of the PLASMAT developers, said: “Compared to other treatments, the combination of these three techniques has improved the effectiveness of cancer cells by 70% to 90%.” In addition, PLASMA is not in the process of treatment. Chemicals are introduced into the body and are less expensive than chemotherapy or radiation therapy. This technology is more mobile than traditional cancer treatments because the required equipment size is small and readily available in most medical settings.
