PDT LASER SYSTEM
Product Details
24 to 72 hours after injecting Photo-sensitizer Drug on the malign tumor, there remains just cancer cell on the spot of the normal cell after disappearing the Photo-sensitizer Drug. At that time, by the cancer cell's being exposed to the LASER the Photo-sensitizer changed into the excited state; otherwise, without the LASER, it returned to the normal state. The cancer cell exposed to the LASER light was dead by the Singlet Oxygen made by the Photo-sensitizer Drug.
