Innovative light therapy reaches deep tumors
Using a mouse model of cancer, the Achilefu Lab have devised a way to apply light-based therapy to deep tissues never before accessible. Instead of shining an outside light, they delivered light directly to tumor cells, along with a photosensitive source of free radicals that can be activated by the light to destroy cancer. And they accomplished this using materials already approved for use in cancer patients. The study appears March 9 in the journal Nature Nanotechnology. Congratulations to the authors - Samuel Achilefu, Nalinikanth Kotagiri, Gail Sudlow and Walter Akers!

The titanium dioxide nanoparticle is shown here (purple)

carrying the iron-binding protein transferrin (blue and green)

and the light-sensitive cancer drug titanocene (red).



The fluorescence goggle system developed by ORL was used for image guided biopsy of the sentinel lymph node in a breast cancer patient.
