Research therapeutics for Photodynamic Therapy (laser-activated photosensitizers).  Photodynamic therapy (PDT), the treatment of disease with light and a light-activated therapeutic agent, has made strides towards a more general clinical acceptance over the past decade, but still has not reached the stage where it is recognized as a first line or primary treatment for solid subcutaneous cancerous tumors by most clinicians, including most surgeons and radiation oncologists. Until now.

the   future

The space and facilities occupied by SensoPath Technologies for the past 10 years have been re-purposed by its owners, requiring us to close and vacate our synthetic laboratories and offices as of May 1, 2017.  WE NO LONGER HAVE PRODUCT IN STOCK AVAILABLE FOR SALE AND NO MEANS TO MAKE NEW MATERIAL, HOWEVER LICENSING AGREEMENTS FOR PRODUCT SYNTHESIS, MANUFACTURE AND DISTRIBUTION ARE AVAILABLE  We are currently in the process of closing the company and entering retirement.  Please  contact:, or phone  406-223-1608 for any questions, consultation or licensing information.  PLEASE REFRESH YOUR BROWSER TO SEE PREVIOUS  PRODUCTS Contact Brenda Spangler for additional product information.
