   Modulight Spotlights: LASER-SHARP RESEARCH – September 2022 Mesothelioma is a form of pleural cancer originating primarily from asbestos exposure. There is currently no curative treatment available for this cancer and its prevalence is on the rise, hence new treatment options are urgently needed. To answer this need, Professors Timothy C. Zhu and Keith Cengel with their teams at University of Pennsylvania have for several years studied intraoperative photodynamic therapy, where photosensitive drug is locally activated with laser light, as a potential new adjunctive treatment for this aggressive disease. Their most recent Continue reading →

Kim, Arash Darafsheh   Effective treatment delivery in photodynamic therapy (PDT) requires coordination of the light source, the photosensitizer, and the delivery device appropriate to the target tissue. Lasers, light-emitting diodes (LEDs), and lamps are the main types of light sources utilized for PDT applications. The choice of light source depends on the target location, photosensitizer used, and light dose to be delivered. Geometry of minimally accessible areas also plays a role in deciding light applicator type. Continue reading →
