Scientists in the United States have recently developed a new technique for storing photos, videos, and other document information with nanoparticles suspended in water. This kind of data storage method called "wet computing" is expected to be used to create better human brain implant devices, which will greatly increase people's brain power, allowing them to make faster calculations or recall more information.
In the latest study, scientists at the University of Michigan borrowed so-called "gum clusters" (a type of microparticle that, when placed in liquids, can change state) to store information. The researchers stated that this change in state of nanoparticles can be used like 0 and 1 to encode information. Moreover, a tablespoon of such nanoparticle liquid can store about 1TB of information, enough to store 2000 hours of audio.
Sharon Grotze, a professor of chemical engineering and materials science at the University of Michigan who led the study, said: “We hope to demonstrate through the latest method that by using nanoparticles, we can store information in a different way than traditional silicon chips. ."
Professor Grotez said that this combination of nanoparticles resembles a Rubik's cube, revolving around a center. Moreover, a "storage cluster" of 12 nanoparticles connected to a central sphere has about 8 million unique states, equivalent to 2.86 bytes of data, enough to encode three text characters.
Grotze explained that if scientists can calculate all the different models and figure out how they can change from one state to another, they can hope to use this method to encode information.
According to a report in the British "Daily Mail", in the latest study, the research team produced a "colloidal cluster" composed of four particles, which are placed on a central sphere. When the liquid is heated, the sphere will gradually become larger and the nanoparticles will self-reorganize in a predictable manner.
However, in order for this liquid storage to be used, they need to find a way to lock the colloidal tufts in large amounts of liquid into the correct shape.
The researchers said that in addition to enhancing the brain's brain power, the more direct use of this technology may be to make biocompatible sensors to monitor the glucose concentration in diabetic patients.
However, the technology still has a long way to go in order to be used in the human body. Researchers claim that their initial use is likely to be used on "flexible robots." The study was published in the latest issue of Soft Materials magazine. (Liu Xia)
