Aerosol with nanobots

03.08.2018

Scientists from the Massachusetts Institute of Technology have created the world's first aerosol containing nanobots. The discovery could radically change the development of robotics. These nanobots can do almost everything from detecting dangerous leaks in pipes to diagnosing health problems.

Each sensor in an aerosol spray consists of two parts. The first is a colloid, a tiny insoluble particle or molecule. Colloids are so small that they can float in air or water forever - the force of the particles colliding around them is greater than the force of gravity.

The second part is a complex circuit consisting of a chemical detector built from a two-dimensional material like graphene. When this sensor encounters a certain chemical in the environment, its ability to conduct electricity is enhanced. The circuit also features a photodiode, a device capable of converting light around it into electrical current. It provides the system with the energy needed to collect data and the nanobot's memory.

The researchers grafted the circuit onto colloids, thus giving the latter the ability to travel in unique environments. After combining, the scientists gave the nanobots the form of a spray, that is, they can now be sprayed. This delivery method would not be possible without colloids. "The circuits couldn't exist without a substrate," says study lead author Michael Strano. "We had to embed the circuits into the particles to give the system strength and also make it big enough for the bots to travel with the flow."

What are these nanobots for? Scientists have demonstrated several ways to use them. For example, they designed sensors to detect poisonous ammonia and tested this ability in a section of pipe. They sprayed the sensors from one end and collected them from the other with gauze. By analyzing the information in the diagrams, they were able to tell if the sensors had come into contact with ammonia.

In the real world, the technology could save inspectors the trouble of inspecting the entire pipe from the outside by simply spraying nanobot aerosols down there.

The same technology can help diagnose diseases in the human body by traveling through the digestive tract, collecting information and delivering it to doctors.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>
