Magnetotactic bacteria and nanotechnology.

 



Magnetotactic bacteria and nanotechnology. 


What would we do with bacteria, what we could control like a robot?

When we are seeing the article below this text (1), we are seeing how simple the magnetotactic bacteria guidance system is. The term magnetotactic bacteria means bacteria, which is always in direction with Earth's magnetic field. This thing means that this kind of bacteria is a really interesting target to use as a miniaturized robot. 

Moving the groups of those bacteria to a certain direction is very easy and that thing would be happening by using the magnetic fields. That would be a suitable method to control large groups of bacteria.

But what if we would want to move single bacteria in a certain direction. One version is to pull the magnetic crystals away from bacteria and replace those things by using the fullerene stick, which is installed with small size servo-motor, and then that thing would push the protein structure to a certain position. The guidance system of those bacteria is basing the magnetic crystals, which affects the protein Mam Y. Or the magnetic crystals can be pulled together by using the magnet, and then the structure would be turned to wanted direction. 

Connecting bacteria and the camera-equipped miniature submarine would be a fantastic idea. 

That would be quite easy to create, and if we would want to make the bacteria move in a certain direction, we must just the small motor and the stick, which can move those magnetic crystals in a certain direction. If that stick would be connected to the control circuit. Another way to make this thing is just creating the nano-submarine, which would have enough powerful magnet to adjust those magnetic crystals to a certain position. 

The small size nano-submarine that is equipped with magnet can swim ahead this kind of bacteria, and that bacteria will swim after the submarine, and this kind of system would allow the bacteria to make things, what we ever can expect. The nano-submarine would communicate with the control unit by using the wireless communication system. 

There could be many solutions to this kind of systems in the future

And the engines of robots would get their electricity by the same system. The operators can see the things by the camera, which is connected to the submarine. This kind of thing would make possible to create small-sized biological robot, which can be used in many missions. In theory, this kind of manipulated bacteria can be used to clean tubes and even blood veins and remove things like plaque from the head of the Alzheimer patients.

Plasmonic waves can make new waves in quantum technology.

"LSU researchers have made a significant discovery related to the fundamental properties and behavior of plasmonic waves, which can lead ot the development of more sensitive and robust quantum technologies. Credit: LSU" (ScitechDaily, Plasmonics Breakthrough Unleashes New Era of Quantum Technologies) Plasmonic waves in the quantum gas are the next-generation tools. The plasmonic wave is quite similar to radio waves. Or, rather say it, a combination of acoustic waves and electromagnetic waves. Quantum gas is an atom group. In those atom groups, temperature and pressure are extremely low.  The distance of atoms is long. And when an electromagnetic system can pump energy to those atoms. But the thing in quantum gas is that the atoms also make physical movements like soundwaves. It's possible. To create quantum gas using monoatomic ions like ionized noble gas. In those systems, positive (or negative) atoms push each other away.  When the box is filled with quantum gas and som...

What is the difference between TR-3A and TR-3B? And are those planes real?

What is the difference between TR-3A and TR-3B? And are those planes real? Is TR-3B (0) "Black Triangle UFO" or is it only the piece of paper?  The study project, what is used to create advanced ideas for use of the nuclear-powered aircraft. Or is it the study project or black budget aircraft, where lost 2,3 trillion dollars (1)of the stealth bomber were gone. In this text is things, that might seem very difficult to accept, and when we are thinking about things like doubling the object or making it smaller by using huge layers of energy, nothing denies to test those things. But were those tests successful, there is no data about that in public Internet, so we must say that things like doubling the human or aircraft can be tested, but the results can be unknown.  But in the source two is the tale, what seems like impossible, those men, who got Noble Prize put at first time one atom to the box, and hit it with photon one photon in the box and hit it with t...

The interesting coincidence between USS Sea Shadow (1982) and CSS Virginia (1862)

Image I The interesting coincidence between  USS Sea Shadow (1982) and CSS Virginia (1862) Far away from its time is the thing, that you might notice when you see those two images. The upper one (Image I) is portraying the modern naval USS Sea Shadow (IX-529)(1) experimental Stealth ship, which was created by Lockheed-Martin, and the image below (Image II) is portraying the CSS Virginia (2), the ironclad from the Civil War Era. The thing why the hull of the CSS Virginia, what is ironclad from 1862 is that the ammunition of the cannons would not transfer their impact energy to the hull of the ship. And the reason why Sea Shadows hull has this form is that it should point the radar echo away from the hull.  The thing that I must say that CSS Virginia is far ahead its time because that structure is effective against the explosive ammunition, and the slanting armor of tanks like T-34 and Sherman have made them effective. But for some reason, the use of slanting ...
