Rubik's Cube. Perhaps this is one of the most famous puzzles of the present. In the collection of the Rubik's Cube, they are constantly setting new records (if you have your own record, tell them in our chat in Telegram). Moreover, this happens not only by humans, but also by artificial intelligence. However, you can also use the famous puzzle toy for other purposes. For example, a group of scientists from the US and China have created a cube that can help doctors diagnose various ailments very well.
How does Rubik's Cube help diagnose diseases?
In fact, an ordinary cube does not help here. It should contain certain elements. Engadget's Editorial Board, headed by a chemistry professor at the University of Texas at Austin, Jonathan Sessler, has used self-healing hydrogel molecules in combination with a range of chemicals.
These chemicals are indeed reagents for determining various variations in the composition of biological fluids. For example, there have long been test strips for the detection of blood sugar, for the detection of various substances in urine and others. Here we have something similar, which was made only in the form of a magic cube. But why did scientists choose this particular form?
That's interesting: doctors use QR codes instead of drugs.
From a self-healing, reagent-based gyro-gel experts have put together a cube with an aspect ratio of 3 x 3 x 3. At the same time, every face and every side can be coated with its own reagent. In addition, multiple reagents can be placed on each side. Somewhere substances are used to determine ammonia, sugar somewhere, and so on. In general, with this approach, you can make a large number of combinations at a very limited level.
How do scientists want to use the magic cube?
Ultimately, chemists want to be able to make conglomerates of intelligent materials that can display medical information when they are applied to human skin or biological fluids (such as blood). The material can also be used in portable sensors that change color, e.g. For example, when patients with diabetes experience abnormally high or low blood sugar levels. Another application of a new type of Rubik's dice is given by Jonathan Sessler:
Remember how QR codes look like. These are black and white pixel patterns that are in a two-dimensional plane. They are used to store information. We investigate the possibility of encoding information in three-dimensionally aligned color patterns, which theoretically leads to a much higher information density.
In the following video you will learn more about the assembly process for each part of the cube as well as the formation of the entire diagnostic cube. It should be noted that at the moment 24 hours after assembly, parts of the cube are "glued", making reuse impossible. In the future, however, the scientists want to further develop the technology so that the cube becomes reusable and recognizes as many diseases as possible.
