If you find a slice of salmon in your computer in the future, don't be surprised.
Taking salmon for cooking is its usual purpose and it has been the only use for a long time. Now thanks to scientific progress, salmon has one more use: store data!
Strictly speaking, based on the salmon DNA material, a single-write, multiple-reader reservoir was created. First, a piece of film was made from Salmon DNA, and a layer of silver atoms was attached to the surface. Then, two electrodes were attached to both sides. Finally, ultraviolet radiation was used to assemble silver atoms to form a cluster of nanoparticles. This material is “written†after the first power-up. If a low voltage is applied, then only weak currents can pass through. If the voltage is high, then the current that is allowed to pass through is relatively strong. 1 and 0.
At present, this kind of DNA storage device can only store data for up to 30 hours. It is far from being used as a computer part. However, scientists insist that this may be a new idea for the future development of storage technology or for some special storage methods!
