Researchers at the Technical University of Munich, Germany, have developed a new nano-robot electric drive technology that enables nanobots to operate at a molecular plant like a pipeline at a sufficiently fast speed, 100,000 times faster than the biochemical processes used so far. This new research has been published as a cover article in the 19th issue of the journal Science.
Currently, all developed countries are racing to develop new technologies for future nano-factory and hope that one day they will use molecular machines to analyze biological samples or produce drugs like pipeline operations, but traditional methods need to add enzymes, DNA chains or light The function activates the module. With this biochemical switch, the nanobot performs certain tasks, such as ingesting and transporting molecules, which may take several minutes as fast as it takes several hours. The research team led by Professor Friedrich Simer, head of the Institute of Synthetic Biological Systems at the Technical University of Munich, Munich, successfully applied the electric field for the first time to realize the electronically controlled nanobots. The new drive technology is 100,000 times faster than the previous method. Simmel introduced that the principle of the new drive technology is simple: DNA molecules carry a negative charge, and by applying an electric field, biomolecules can move.
In this innovative study, Munich University of Technology also cooperated with the University of Munich. The latter used coloring molecules to mark the tip of the nano robotic arm so that its motion can be tracked by a fluorescence microscope. The researchers used computer control to change the direction of the electric field, adjust the arm's direction, and set the motion process. Simmel said that the electronic control allows nanobots to move at millisecond intervals, which is 100,000 times faster than previous biochemical drives.
The new control technology is not only suitable for moving colored nanoparticles back and forth, but the micro-robot arm can also exert forces on the molecules. Such interactions can be used for medical diagnostics and drug development. Simmel emphasized: "Since the nanobots are small and inexpensive, millions of nanobots can work simultaneously, just like on the assembly line, gradually discovering specific substances in chemical reagents or synthesizing complex molecules."
Do you need a basin of water to blow the air conditioner? Is it better to blow the air conditioner with cold water or hot water
1. Do you need a basin of water to turn on the air conditioner
If you don't use a humidifier at home, it's better to put a basin of water indoors when blowing the air conditioner. Because the air conditioner will take away the moisture in the air during the refrigeration process, the air will be relatively dry. People expect that in the air conditioning room, they are prone to symptoms of dry skin, dry eyes, dry throat and sore throat. Placing a basin of water in the air conditioning room can adjust the humidity of the air and improve the drying condition
2. What is the effect of turning on the air conditioner and putting a basin of water
Blowing air conditioner and putting a basin of water indoors can increase humidity, but the effect is limited. Because the general water basin is relatively small, the degree of evaporation and dispersion of water vapor can not be extended to the whole room, but can only improve the humidity of the air around the water basin. Therefore, in order to reduce the impact of air drying on the human body, it is best to put the water basin close to the human body, and it will have no effect if it is put far away
3. Is it better to turn on the air conditioner to drain cold water or hot water
In theory, hot water is better, but in practice, it's better to put cold water. Because hot water can actively evaporate before cooling, the humidification effect is better than cold water in theory. However, a basin of hot water basically cools in less than an hour, but we can't change a basin of hot water every other period of time, so let's put hot water or cold water at will
4. Blowing air conditioner to dry air can also be done
--The most convenient and effective way to dry the air conditioner with humidifier Aroma Diffuser is to place a humidifier indoors. It can be used for a whole day almost only by adding water 1-2 times a day. However, if the humidifier you buy is not big enough, you'd better put the humidifier close to the human body, otherwise the effect will not be very good.
---Wet the ground and blow the air-conditioned air to dry. If the ground is wet, the moisture on the ground will also improve the humidity of the air-conditioned room after slowly evaporating. If you think it's troublesome to drag the ground every few days, you can sprinkle water on the ground, and the effect is the same. But note that the home is wooden floor, so you can't do this to avoid damaging the wooden floor.
