Laser based techniques and solutions have found large applications in the emerging field of biomedical technology. Some of the common applications are lisled below.

Photodynamic Therapy
Photodynamic Therapy (PDT) combines special drugs called photosensitizers and a specific wavelength of laser light to treat a wide range of medical conditions from cancer to acne and psoriasis. It is gaining popularity, since it is a treatment that is minimally invasive and minimally toxic without the litany of side reactions common with traditional drugs.

Photosensitizers that are used in PDT respond to a particular wavelength of light. When the photosensitizer is activated by the laser light, they form “reactive oxygen” which lead to chemical destruction of specific tissues targeted. Development of high power lasers with fibers have enabled the delivery of regulated amounts of light intravenously to target cells and tumors. PDT has already proven results in curing skin cancer and has expanded in the treatment of other forms of cancer with promising results.

Common wavelengths of lasers used in PDT are UV (315-400nm), 405 nm, pulsed green laser. World Star Tech offers a complete line of lasers in these wavelength ranges. All our standard lasers can be customized to suit the specifications of the application.
