Synthetic photobiology for light controllable active matter

Nature is perhaps the greatest engineer of all time. Scientists strive to mimic natural phenomena and benefit from their inherent efficiency and simplicity. Self-propelled colloids, a type of synthetic active matter similar to self-propelled bacteria, are among the many accomplishments. In addition to the synthetic machinery for motion, scientists have also identified the genetic components required to impart responsiveness to the environment. SYGMA is using the genetic building blocks of functional properties to create light-controllable active matter. Engineered photoreceptors sensitive to red, green, and blue much like cones in the retina will be linked to cellular processes that modulate things like speed, growth, and death. Light control of fleets of mini cargo transporters could be around the corner.
