This technology concept pertains to the stimulation of cells using laser light to create specific growth patterns, or make them grow together faster, or more efficiently. It would essentially be like welding 3D printed cells together. Laser light can also be used to activate neurons, and the intention is to connect neurons together that were not previously connected, such as through the transplant of skin cells or organs. This technology concept is new, so there's no way to know how successful this technology would be, however optogenetics has been successful in communicating with and reading the state of neurons inside nerve cells. Lasers are used to repair vision, and they can be used to cut things - they can also be used to connect things together.
