Researchers at IITGN have created a new cancer treatment that uses gold nanorods to target and destroy cancer cells. This treatment combines chemotherapy with heat generated by near-infrared light, making it more effective than current treatments.
One of the biggest challenges in fighting cancer is finding ways to kill cancer cells without harming healthy cells. Researchers at the Indian Institute of Technology Gandhinagar (IITGN) have developed a new treatment that uses gold nanorods to target and destroy cancer cells.
Gold nanorods are tiny structures made of gold that can absorb near-infrared light and convert it into heat. The researchers used these nanorods to deliver chemotherapy drugs directly to the endoplasmic reticulum (ER), a part of the cell responsible for protein production and processing. They also added a molecule called dansyl-sulfonamide, which helps guide the nanorods to the ER.
The team tested this new treatment on colon cancer cells, cervical cancer cells, and breast cancer cells. The results showed that the gold nanorods were able to accumulate in the ER of these cells, causing them to become stressed and eventually die. When exposed to near-infrared light, the heat generated by the gold nanorods increased the damage caused to the cancer cells.
This new treatment is a major breakthrough in the fight against cancer. It combines the effectiveness of chemotherapy with the precision of targeted therapy, making it more effective than current treatments.
Why It Matters
This new treatment could save lives by providing a more effective way to kill cancer cells without harming healthy cells. As India struggles with high rates of cancer, this breakthrough is especially important for Indian students and researchers who can build upon this discovery to develop even more innovative treatments.
