Rubik's Cube. Perhaps this is one of the most famous puzzles to date. In the collection of the Rubik's Cube, they constantly set new records (if you have your own record, share it in our chat in Telegram). Moreover, this is done not only by people, but also by artificial intelligence. However, you can use the famous puzzle toy for other purposes. For example, a group of scientists from the USA and China created a cube, which (just do not be surprised) can very well help doctors diagnose various diseases.
How does Rubik's Cube help diagnose diseases?
Strictly speaking, an ordinary cube will not help here. It should contain certain elements. According to the editorial staff of Engadget, a group of experts led by a professor of chemistry at the University of Texas at Austin Jonathan Sessler used molecules of a self-healing hydrogel combined with a number of chemicals in its work.
These chemicals, in fact, arereagents for determining various deviations in the composition of biological fluids. For example, for a long time there are test strips to detect blood sugar, determine the presence of various substances in the urine and others. Here we have something similar, only made in the shape of a Rubik's Cube. But why did scientists choose this particular form?
This is interesting: Doctors will use QR codes instead of drugs.
From self-healing gyro gel basedreagents, experts collected a cube with an aspect ratio of 3 x 3 x 3. Moreover, on each face and each side can be applied "your" reagent. Moreover, several reagents can be placed on each face. Somewhere substances are placed to determine ammonia, somewhere sugar and so on. In general, this approach allows you to form a huge number of combinations on a very limited plane.
How do scientists want to use the Rubik's Cube?
Ultimately, chemists want to be able tocreate conglomerates from smart materials that can display medical information when placed on human skin or when placed in biological fluids (e.g., blood). The material can also be used in wearable sensors that change color, for example, when it detects abnormally high or low blood sugar in patients with diabetes. Another application of a new type of Rubik's cubes leads Jonathano Sessler:
Remember how QR codes look. These are black and white pixel patterns located in a two-dimensional plane. They are used to store information. We are studying the possibility of coding information in color patterns oriented in three dimensions, which theoretically leads to a much higher density of information.
In more detail on the assembly process of each partcube, as well as the formation of a whole diagnostic cube, you can on the video, available below. It is worth noting that at the moment 24 hours after assembly, parts of the cube are “glued”, which makes it impossible to reuse it. But in the future, scientists plan to refine the technology so that the cube becomes reusable and recognizes as many diseases as possible.
