当光敏剂血卟啉及其衍生物(HPD)注入体内后,能选择性被恶性肿瘤吸收并潴留于肿瘤内。在405或436 nm波长的光照下,产生荧光;在630 nm波长的光照下,产生光动力化学反应,杀伤肿瘤细胞。这就是血卟啉光敏技术的基本原理,目前已用于某些
When the photosensitizer hematoporphyrin and its derivatives (HPD) are injected into the body, they can be selectively absorbed by malignant tumors and retained in the tumor. The fluorescence is generated at a wavelength of 405 or 436 nm, and the photodynamic chemical reaction is generated at a wavelength of 630 nm to kill the tumor cells. This is the basic principle of hematoporphyrin photosensitizing technology, which is currently used in certain
