                                 <p>Our system utilizes <em>Escherichia coli (E. coli)</em> bacteria that are producing the <a>photosensitizing protein KillerRed</a> (KR). When illuminated with light, the KR fluorescent protein (580/630nm) produces <a>Reactive Oxygen Species</a> (ROS). These species irreversibly damage cell proteins, membranes, and DNA, ultimately leading to cell death [2]. Bacterial growth is monitored by measuring the fluorescence of cells containing KillerRed, and population control can be achieved by modulating the amount of ROS produced inside the bacteria with light stimulation. Since the amount of ROS produced is closely related to the amount of intracellular KillerRed, a photosensitive system [3-4] was developed to regulate the concentration of this protein.<br><br>
