Design of a Multi-Use Photoreactor to Enable Visible Light Photocatalytic Chemical Transformations and Labeling in Live Cells.

Despite the growing utilization of visible light photochemistry in both chemistry and biology, a general low-heat photoreactor for use across these different disciplines does not exist.  Herein, we describe the design and utilization of a standardized photoreactor for visible light driven activation and photocatalytic chemical transformations. Using this single benchtop photoreactor, we perform photoredox reactions across multiple visible light wavelengths, a high throughput photocatalytic cross coupling reaction, and in vitro labeling of proteins and live cells. Given the success of this reactor in all tested applications, we envision that this multi-use photoreactor will be widely used in biology, chemical biology, and medicinal chemistry settings.
