Although existing laser treatments such as ultraviolet irradiation bypass the problem of drug resistance, such treatments usually have clinical side effects. For example, ultraviolet radiation is known to cause cancer and can kill healthy cells in the process of destroying pathogenic microorganisms. Instead of using these traditional techniques, the new method uses vibrations from a femtosecond laser to break the links among...Read full article
