Researchers Tardigrades. They consider it be useful

Deficiency manufacturing It is – specifically – building small things, including things, microscopic patterns and endoscopes. Define manufacturing has great potential in medicine and biomedical engineering, as well as areas such as electronics and visible – but first, researchers need to develop biologically compatible techniques. One team of researchers believes that the decisive step towards this goal includes clarify tardigrades.

In order to test the techniques needed to build compatible devices with microscopic devices, researchers in China found a way to give Tardigrades. If you think this is a fool, just wait. Their approach, detailed in a Ticket It was published at the end of March in Nano Letters, which can have important effects on the development of live Microbotics, such as the microbial Cyborgs.

In fact, tardigrades, also known as water bears, are not just the “Hardy” creatures. They are eight -legged animals about 0.02 inches (0.5 mm), and they are almost not destroyed. Their amazing resistance to hunger, frozen temperatures, radiation, pressure, and space emptiness, in an amazing way, inspired scientists to investigate whether human beings can learn something Or two Among them.

In the recent study, the researchers drought tardigrades to urge an encrypted condition-a type of half-dead hibernation. Put tardigrades on the refrigerated surfaces to less than -226 degrees Fahrenheit (-143 ° C), and cover the small creatures in the ansal, an organic compound of forgetting.

Using a concentrated electron beam, the researchers drew Micropatterns on Tardigrades such as squares, lines, points and even university logo. The frozen anisole layer, which was exposed directly to the package, formed a new chemical compound that has been adhered to to Tardigrade. Then the team heated Tardigrade to room temperature under a vacuum, and the frozen ansecol that did not interact with the beam of the electron that was subjected (turned into gas), leaving behind the style created by only the new tattoo – tattoo. Then they finished Tardigrades.

The good news is that the tattoo does not seem to affect the revived tardigrades. Bad news is that only about 40 % of Tardigrads have survived, but researchers say this can improve with more improvement. However, the study indicates that researchers can use this method to print electrical appliances or sensors on live tissues.

The researchers wrote in the study: “This approach provides new visions about the flexibility of tardigrades and has possible applications in maintaining cooling, biomedics, and astronomy,” the researchers wrote in the study. Cooling the cooling It is the practice of preserving the biological material at very low temperatures. “Moreover, the incorporation of nano -manufacturing techniques with living organisms can stimulate progress in biological sensing, biomass science, and living life.” Vital It involves the tradition of nature operations in human creativity.

Microbots is small robots that can perform tasks inside the body of the organism, like Providing medicine, monitoring and treating diseases. As such, we can assume that live microbots, like CYBorgs microbialThey are hybrid robots that join artificial technology and living cells to achieve more useful features.

“Through this technology, we are not only creating small tensions on tardigrades- we are expanding this ability to many living organisms, including bacteria,” said Deng Zhao, the co-author of the paper and researcher at the Weettel Electron Institute. statement.

“It is difficult to organize the living issue,” said Javin King, a researcher in the Department of Physics and Astronomy at Missouri University. The credit for the king’s statement with the invention of the technique used in the study, and it is called ice stone printing. He concluded by saying: “This progress predicts a new generation of biological devices and vital physical sensors that were previously present in science fiction.”
