Sunstone BioSciences, Inc., in conjunction with Princeton University, National Cancer Institute and the University of Pennsylvania, are seeking to discover non-invasive techniques for treating cancer.

In Vitro - PDT with up-converting nanoparticles shows complete cell kill for mesothelioma and bronchioloalveolar lung cancer cell lines.

In Vivo - "Upon treatment utilizing external infrared excitation of a currently FDA-approved photosensitizer, mouse lung cancer models showed little or no evidence of tumor growth.”
- University of Pennsylvania

Sunstone Nanoparticles are rare-earth oxide and oxysulfide nanocrystals that absorb electromagnetic energy at specific wavelengths and convert it to photons at different energy levels.

Micron sized particles have been used for security applications for many years. The ability to produce the particles on a nano scale opens endless possibilities for In-Vitro and In-Vivo medical applications.

Sunstone BioSciences, Inc. is currently developing up-converting nanoparticles as photosensitizer delivery and activation systems that will allow for preferential tumor uptake and provide greatest tumor destruction.
