Unexpected discovery: Salmon not only to eat!

Smoked salmon, grilled salmon or sushi rolls are all excellent dishes.But with the latest research of Taiwan Tsinghua University and the German Karlsruhe Institute of Technology, salmon can also be a great data storage device of the future.

Using silver nanoparticles, electrode electrodes and a thin film of salmon DNA, the scientists created a storage device 'write once, read many times' (WORM) with superiority to Can completely replace silicon.

Basically, the mechanism of operation of this device is based on how the silver atom moves inside the thin film. When UV light is applied to the system, the silver atoms will collide with the nanoparticles inside the film. Attaching two electrodes to both sides of the film, you will have an optical data storage device, Popsci said.

When there is no (or very little) current flowing through the device, the device will be in the 'off' state . If you slowly increase the voltage, the device will switch to 'on' mode . In other words, the current will create two 'off' - continuous 'on' states like electrons and systems so that data can be stored like any other optical storage device, homes. explained science.

They hope this discovery could open up completely new design directions for future optical drives.

This is not the first time that researchers think that DNA has a storage effect. Previously, Imperial University London created a logic gate from DNA and bacteria, while American scientists genetically modified the E. coli bacteria and took its DNA genome to solve a mathematical math puzzle.
