The Rubik’s Cube. Perhaps this is one of the most famous puzzles today. In solving a Rubik’s cube constantly put all the new records (if you have your record, share it in our chat in Telegram). And do it not only people, but also artificial intelligence. However, you can apply the well-known toy-puzzle and for other purposes. For example, a group of scientists from the USA and China have created a cube that (but not surprised) can help physicians diagnose various diseases.
Like a Rubik’s cube will help in the diagnosis of diseases?
Strictly speaking, the standard cube has nothing to do with. In its composition must contain certain elements. As transfers the edition of Еngadget, a group of experts headed by a Professor of chemistry at the University of Texas at Austin Jonathan Sessler in their work used the molecules self-healing hydrogel connected with a number of chemicals.
These chemicals, in fact, are reagents used to identify various abnormalities in the composition of biological fluids. For example, there are long test strips to detect blood sugar levels, determine the presence of different substances in the urine and others. Here we have something similar, only in the shape of the Rubik’s cube. But why the scientists chose this form?
From self-healing geroges-based reagents, the experts have gathered a cube with sides in the ratio 3 x 3 x 3. At the same time on each side and each side can be applied to “your” agent. Moreover, on each face you can put a number of reagents. Somewhere are used, to find the ammonia somewhere sugar and so on. In General, this approach allows us to generate a huge number of combinations on a very limited plane.
How scientists want to use a Rubik’s cube?
Ultimately, chemists want to be able to create conglomerates of smart materials that can display medical information when placed on human skin or when placing materials in a biological fluid (e.g. blood). The material can also be used in wearable sensors, which change colour, e.g. when it detects abnormally high or low blood sugar in patients with diabetes mellitus. Another use for the Rubik’s cube of a new type leads Jonathan Sessler:
Remember, the look of QR codes. This black-and-white pattern of pixels located in the two-dimensional plane. They are used to store information. We are studying the possibility of encoding information in the color patterns oriented in three dimensions, which theoretically leads to a much higher density of information.
More detail on the Assembly process of each part of the cube, as well as the formation of a whole diagnostic of the cube, you can video, available below. It is worth noting that at the moment, 24 hours after assembling the parts of the cube stick together, making it impossible to reuse. But in the future, the researchers plan to Refine the technology that the cube was reusable and recognize as many diseases.
