Our Technology

We use laser light and non-toxic compounds derived from natural products to  detect and treat cancer.

In PDT the directed laser light excites the photosensitizer accumulated  inside the tumor tissue to a higher energy state. The excited photosensitizer interacts with oxygen present inside the  tumor and produces reactive oxygen species (mainly singlet oxygen), which destroy the tumor cells and tissue.

PDT technology has been successfully used to treat lung, esophageal , oral and other head & neck cancers

Certain selected PDT photosensitizers can also be used for the treatment of cancer by sonodynamic therapy, where instead of light, ultrasound is used to excite the PS. The mechanism of tumor cell kill by SDT is similar to PDT.
