Non display non lighting applications, LED technology is expected to help cure cancer.

In addition to display and lighting, the application of LED technology in the medical field is also progressing. It is found that LED technology has created possibilities for the treatment of cancer.

It is reported that researchers at Waseda University in Japan have developed an implantable device consisting of LED chip and bioadhesive nanosheet, which can successfully reduce tumor in mice by photodynamic therapy. The research results were published in Nature Biomedical Engineering journal in July 16, 2018.

Rhythmic photodynamic therapy is a long-term treatment with low doses of special drugs and special lighting to kill cancer cells. In order to use rhythmic photodynamic therapy, researchers have implanted implantable devices in the surface of animal tissues, where the device can release low-intensity radiation to treat targeted lesions, so as to achieve therapeutic goals.

The research team said that compared with traditional photodynamic therapy, the device reduced the light intensity by 1000 times, which could avoid injure normal tissues and effectively treat tumors. According to research team leader Toshinori Fujie, surgery or radiation therapy for cancer of the brain or pancreas and other parts of the body is risky. Implantable devices may play an important role in treatment.

Specifically, it is possible to reduce the threat to healthy areas by installing rhythmic photodynamic therapy devices directly in targeted lesions. (compile: LEDinside Janice)
