An In-House-Built and Light-Emitting-Diode-Based Photodynamic Therapy Device for Enhancing Verteporfin Cytotoxicity in a 2D Cell Culture Model

Here, we describe a novel, simple, and low-cost device to successfully perform in vitro photodynamic therapy (PDT) assays using two-dimensional HeLa cell culture and verteporfin as a photosensitizer.
