1. LED may be used as a substitute for laser to treat cancer
According to media reports, Professor Ivy Hsu from the Department of Biological Science and Technology of Chung Yuan Christian University introduced a research discovery at a press conference held by the Ministry of Science and Technology of Taiwan, announcing that his research team has discovered that LEDs can replace lasers in the treatment of cancer. Taiwan has always imported laser equipment produced in the United States, but the cost of each laser equipment is as high as NT$1.5 million (approximately US$4.58 million). The research and development project initiated by Professor Hsu aims to demonstrate the luminous efficacy and performance of LED lamps in the results of photodynamic therapy.
According to a professor, the LED light source can achieve a power density of more than 635nm and is compatible with the laser light intensity, showing a better treatment effect in the preclinical test study of the hamster oral and cheek pouch precancerous lesion model. Researchers pointed out that Taiwan is one of the largest LED production bases in the world, with advanced high-brightness LED light source technology. These findings indicate that the Taiwan market can reduce its dependence on foreign laser sources by adopting laser substitutes in the future.
2. Short-wave ultraviolet uvcled has great medical potential
As a new generation of LED technology can help prevent or even eradicate deadly diseases, UV LEDs (ultraviolet light-emitting diodes) are becoming increasingly important. It is understood that UV LED not only enables humans to obtain clean and pure water, but can even be used to eliminate diseases such as Middle East Respiratory Syndrome (MERS) and Ebola virus. Compared with visible light lamps, ultraviolet lamps have shorter wavelengths. In particular, UVC (short-wave ultraviolet light emitting diode) lamps can effectively kill bacteria and prevent microbial regeneration from causing water pollution.
