Chapter 668： 【New bio-nano transistor】

Traditional chips are not compatible with organic life. The so-called chip implantation is by no means what most people think is to implant traditional chips into the human body. This will cause serious rejection and naturally cannot be applied to the use of biological Technical bionics can only be intelligent machines, and intelligent robots cannot achieve the confidentiality effect that Luo Sheng wants.

Another reason is that even if the traditional chip can be used in a compatible manner, it also means that a battery needs to be installed in the bionic human body to power the chip. This is very power consuming and is obviously a poor design that Luo Sheng cannot accept.

Only a chip composed of biotransistors can solve the compatibility problem with organic living organisms.

It should be known that although bioelectricity and the electricity used by people in daily life electronic devices both carry the word "electricity", the two are not the same thing, and they are very different in nature.

To transform bioelectric signals generated by living organisms into electronic signals for controlling machines without distortion, at present, no one has done it. At least no one in the world has done this before Luo Sheng fully invested in it.

But if this is not possible, even if a powerful chip core is installed in the bionic human body, it is impossible to use it as sensitive as a real organ.

In the following days, Luo Sheng alone and Xiao Na's assistance began to overcome this technical problem, which required him to master and master the knowledge of multiple subjects at the same time.

The principle is not difficult to understand, and even contains basic physics knowledge at the middle school level.

The movement of charge forms a current, so-called "carriers", which can be positive or negative. At present, all current electronic devices use electrons as carriers and carry negative charges.

But the difference is that the so-called bioelectricity in organic life is very different from this. There are some special channels in the cell membrane of the organism. When the concentration of ions inside and outside the cell membrane is unbalanced, these channels will open. Sodium and potassium 、Calcium and other ions are released from the cells or flow in from outside the cells, thereby forming bioelectricity.

Humans can control their bodies based on this. Without swimming in these ions in the body, they can’t lift their hands and kick their legs, or even see the outside world, because electrical signals are transmitted from the retina to the nerve center of the brain. , Relying on the same set of mechanisms.

Bioelectricity is generated by the movement of ions, and these ions carry a positive charge.

In other words, the electronic devices made by humans and the current carriers in the human body are not the same kind of particles at all. It is also very simple if you want to enable the perfect interaction between the living body and the electronic devices. Bioelectrical signals are "translated" into electronic signals, or electronic signals are "translated" into bioelectrical signals.

It is simple to say, but not everyone can do it, and it must take into account that a lot of rich details will be lost during the "translation" process, resulting in signal distortion.

The seventeenth day of retreat.

...

In the laboratory, Luo Sheng is still silently researching, and several display panels are related to the research papers. These are all papers published by other scholars in the industry. Of course, Luo Sheng should also be used for reference research.

Xiao Na's voice suddenly resounded in the quiet laboratory, "Master, today you are working for more than 15 hours a day for 16 consecutive days. Your physical data shows that the brain is now in an over-fatigue state. You really need Take a good rest."

Luo Sheng slid one of the display panels, staring at the above paper and analyzing it lightly and said, "It’s not to tell you that it’s okay, don’t monitor my physical condition. You want to help me, not block me, you know?"

Xiaona replied, "Okay, then"

During this time, Luo Sheng is not only conquering technical problems, but also unconsciously has mastered three brand-new knowledge in order to overcome the problems, and has reached the point of mastery. This is the best interpretation of one pass.

In Luo Sheng's design ideas, the ideal machine for dealing with biological cells needs to have two basic conditions. First, it is compatible with organic life, and will not be rejected; second, it communicates with the cell's own language.

In other words, the best way to transmit electrical signals is to carry positively charged particles, so that you can control the positive and negative ions on the cell membrane.

This idea leads directly to biotransistors.

In the daily life of common electronic devices, the soul of the device is the transistor, which is also the basic element of the chip. The transistor is essentially an electronic switch that controls the current. Applying an external electric field to it can determine whether it is turned on or off.

When humans just invented transistors, a single transistor was as long as 1 cm long. With the advancement of technology and the rapid development of integrated circuit industry technology, a fingernail-sized chip can now accommodate tens of billions of transistors. Too.

In the next few days, Luo Sheng made a small part of his own in the laboratory, which can realize the function of a transistor, but it does not control electrons, but positively charged ions.

In addition, it is also compatible with living organisms, so-called biotransistors.

Like biologists who have struggled to develop biotransistors for decades, Luo Sheng used sodium, potassium, and calcium ions to pump ion pumps into cells. Unfortunately, the materials used are not compatible with living organisms.

In the following week, Luo Sheng tried a variety of methods and the test ended in failure.

In an instant, the time came to June.

It was dinner time at this moment. There was a whole table of hearty dishes on the table. There were four people on the table, namely Luo Sheng, Qin Weimu, Irene and An Qingxue.

It can be called a rare famous scene.

Strictly speaking, the little princess An Qingxue is pregnant with is five people.

There is a delicious dish made of hairy crabs from Yangcheng Lake on the table, but this is not suitable for An Qingxue during pregnancy. It is more taboo to be pregnant. Her meal...

Drinks are specially arranged.

At this time, An Qingxue suddenly looked at Luo Sheng and said, "Brother, can you promise me something?"

"whats the matter"

Luo Sheng responded casually. He was also multi-tasking at the same time as he was eating, thinking about the bio-transistor. Recently, he was a little depressed by this problem.

"Work hours will be halved from tomorrow, and you will resume working eight hours a day. Even if you don’t think about your physical exertion, you have to consider our feelings, and the daughter who will be born."

Hearing this, Luo Sheng couldn't help but stunned, and immediately looked up at the Qingxuemei paper, and then looked at Aileen and Qin Weimu, they didn't say anything, it seemed like nothing to do with each other, but in the sight of them When his eyes met, he saw a taste of being bitter and cold.

Luo Sheng realized that almost all of his energy was spent on technical research during this time, and he really only paid attention to the research. When he thought of it, he immediately nodded and smiled, "Well, I promise you."

But at this moment, when Luo Sheng looked at the plate of hairy crabs on the dining table, he suddenly realized the same moment.

"I think I have found a solution. You have to eat it. I have to go to the laboratory first." Luo Sheng suddenly got up from the dining table and went to the laboratory with a cry, pretending not to see Qin Weimu. , Irene They complained with full eyes.

Only last one second

After a while, Qin Weimu said lightly, "It's not only men who can solve the demand problem with their own hands, women can also do it. Xiao Ai will play with us later."

An Qingxue ""

Xiao AI ""

The two faces froze for a while. UU Reading

What kind of tiger and wolf is this

On the other side, Luo Sheng took a trip to the kitchen with a bag of fresh hairy crabs and brought it to the laboratory before going to the 32nd floor laboratory.

It was when he saw the crabs on the dining table that Luo Sheng suddenly realized that chitin fiber can be extracted from the crab shell, and chitin fiber is the only positively charged polymer material in nature.

This is not the best material for the biotransistor I want to make

It was night, Luo Sheng alone extracted the polymer material from the hairy crab shells into a nanofiber tube made of this material in the laboratory, allowing protons to flow.

Applying an external electric field to it can also determine whether the proton flow is accelerated or stopped, and this material is soft and tough, and is well compatible with biological organisms.

At three o'clock in the morning, Xiao Na's voice responded with joy in the laboratory.

"Congratulations, master, you finally made the world's first biotransistor."

Luo Sheng couldn't help laughing, and said, "I finally found a solution. This step is easy to go over and below, everything will come naturally."

Unexpectedly, the problem was solved by crabs in the end.

However, there are still many problems until the actual production of usable biochips, then...

The next step is to solve the problem of chip integration and biochip design. These links are no different from traditional chips, and existing chip design and manufacturing related technologies can all be technically supported.

Luo Sheng couldn't help but yawned. After overcoming the problem, fatigue instantly struck. He stretched out and left the laboratory.

Finally I can take a good rest.
