The future of medicine is here: light-activated molecular machines! Scientists have recently developed a new type of molecule which can be triggered by a single light pulse. The molecule, called a photoswitch, can be used to control the functions of cells. When the light is shined on the molecule, it triggers a reaction that causes the cell to act in a certain way. This could be used to create treatments for a wide variety of diseases, such as cancer, or to develop new drugs. It could even be used to control the behavior of cells, such as regulating their growth. This new technology could revolutionize the medical field and provide us with a new way to treat a variety of conditions.
