Chapter 308 Returning with Hope
Looking at the ultrasonic nano-preparation device in front of him, Zhao Heng couldn't help but feel in a trance for a moment. Just two months ago, he was a very hard-working low-level hospital equipment supplier, but now, he is actually in the country or even In the world's top laboratories, carbon nanotubes, a high-end material that only appeared in science fiction movies or novels more than ten years ago, can also be independently prepared.
Carbon nanotubes are allotropes of carbon nanostructures, and their length and diameter are 1 or more larger than carbon nanostructures. The excellent physical and chemical properties of carbon nanotubes make these cylindrical carbon molecules There are new properties in many applications of nanotechnology, especially its unique surface area, stiffness, strength and elasticity, making carbon nanotubes have always been a hot research topic in the field of pharmaceuticals.
For the preparation of carbon nanotubes, it is not very perfect at present. The preparation methods of carbon nanotubes mainly include arc method, laser evaporation method and chemical vapor deposition method, but the preparation process conditions of these methods are relatively difficult to control, resulting in quality and Yields are relatively low.
Therefore, under the leadership of Professor Li Hongwei, a new carbon nanotube preparation method has been explored, which is the ultrasonic nano-preparation device, which is the silver-white instrument in front of Zhao Heng.
This instrument seems to be only the size of an ordinary machine tool, but it is worth at least 5000 million. It can be said that this is a priceless equipment, not to mention that this equipment was independently developed by the scientific research team led by Professor Li Hongwei. Worldwide, the carbon nanotubes prepared by it are top-notch in terms of quality and output.
It can be seen from here that Professor Li Hongwei gave Zhao Heng the authority to enter here alone and operate this equipment independently, which is a great trust.
As a medical student who graduated from a medical university, it was difficult for Zhao Heng to get started with the cutting-edge technology of carbon nanotube preparation, but with the system, he had picked up the corresponding technology from Professor Li Hongwei before.
Here, I have to talk about the principle of this ultrasonic nano-preparation device. The use of ultrasonic waves to prepare carbon nanotubes is to apply ultrasonic waves in the liquid. When the ultrasonic waves are strong enough, the liquid will produce a The group of bubbles, each of which is a hot spot, is simultaneously affected by strong ultrasound.
After going through the sparse phase and compressed phase of ultrasound, the bubbles grow, shrink, re-grow, and re-shrink, undergo multiple periodic oscillations, and finally collapse at a high speed.
In the process of periodic oscillation and cracking, a high temperature of up to 2760°C and a high pressure of about 5.05 times 10 to the eighth power will be generated, accompanied by strong shock waves and micro jets up to 400km/h. This micro jet, An extremely strong mechanical stirring effect will be formed between the interfaces, which can break through the limitation of the laminar boundary layer, strengthen the chemical reaction process and transfer process between the interfaces, thereby promoting the decomposed carbon atoms to precipitate on the catalyst particles, and finally form carbon nanotubes.
Although described, the process of carbon nanotube preparation seems very simple, but the actual situation is not the case.
Among other things, the silver-white reactor in front of Zhao Heng, which can accommodate high-temperature and high-pressure reactions, cannot be manufactured casually.
As far as the one in front of Zhao Heng is concerned, Professor Li Hongwei contacted an engineering academician and entrusted this academician to lead his professional team to prepare it.
Therefore, every step of scientific research is very difficult, and many conditions must be met.
Research in a certain field has stagnated for many years, which is nothing more than a normal thing in the field of scientific research.
But now, Zhao Heng can be said to be standing on the shoulders of giants. The preparation and application of nanotubes is not just the result of Professor Li Hongwei alone.
Professor Li Hongwei told Zhao Heng before that his research project was, to some extent, inherited from his teacher, an old academician.
In some major scientific research fields, it may take not only the efforts of one generation, but even several generations, to break through a certain bottleneck and turn a certain theory into practical application.
The process of preparing carbon nanotubes is automatic. Zhao Heng only needs to adjust the parameters and start the machine to automatically generate carbon nanotubes in the reactor.
The size of carbon nanotubes allows them to pass directly through the cell membrane and enter the nucleus without causing damage to the cells. At the same time, the cells will not think that carbon nanotubes are harmful invaders. After entering the cell, the carbon nanotubes will directly carry the Molecules injected into the nucleus, in order to complete the transport and precise release of drugs.
The next step is to load the drugs to be carried on the carbon nanotubes.
Because in order to realize drug transport, it must rely on two aspects of work, one is the loading of drug molecules in carbon nanotubes, and the other is the transport of drug molecules in carbon nanotubes and the release at the target position. , also known as the molecular pump.
Regarding research in this area, Professor Li Hongwei led his team, and the research is already very mature, and the drug miltefucin is also in stock in the drug library of the biological laboratory of Yenching University. Before entering the laboratory , Zhao Heng has already gone to get it.
In this way, under Zhao Heng's very skillful operation, at eleven o'clock in the evening, Zhao Heng finally prepared a tube of carbon nanotubes loaded with mitifusin.
Looking at the time, it was already eleven o'clock in the evening. Before he knew it, Zhao Heng had already been in the laboratory for five or six hours. When he was concentrating on his work, the time passed so quickly.
Zhao Heng couldn't help looking at the silver-white metal can in his hand. Inside this metal can was the most cutting-edge research results, carbon nanotubes loaded with mitifoxin. It can be said that this kind of carbon nanotubes that can be used in practice, Even in the world, it is the most cutting-edge scientific and technological achievements.
Thinking of this, a sense of pride welled up in Zhao Heng's heart, because this achievement, from the proposal of the theory, to the establishment of the project, to the present achievement, was independently researched by Chinese scientists. Said to be very commendable.
After packing the can of extremely precious carbon nanotubes in a metal box, Zhao Heng turned off the equipment and left the laboratory.
Carrying the metal box, Zhao Heng came to the gate of Yenching University. As soon as he arrived at the gate, Zhao Heng saw Liu Ziang in a white coat standing beside an ambulance, as if he was waiting for him.
"You finally came out. I thought I was going to stay here all night. I've already figured out what to eat."
Seeing Zhao Heng coming out with the metal box, Liu Ziang, who was standing next to the ambulance, also let out a long sigh of relief.
"It's fine if you come by car, why do you still drive an ambulance?"
Seeing Liu Ziang driving an ambulance alone, Zhao Heng couldn't help asking while holding his forehead.
"Fast ambulance!..."
Hearing what Zhao Heng said, Liu Ziang also said helplessly.
In an emergency, an ambulance can bypass some traffic rules. In the traffic conditions in Beishi, if he drives his own car, he may not be able to arrive in two or three hours when he returns. This is not a delay. what. .
Originally, the courtyard said that the people from the emergency center would come by car, but Liu Zi'ang thought about it, and he didn't know when Zhao Heng would come out. Wouldn't this take up a spot as a driver in the emergency center?
Thinking of this, Liu Ziang found an ambulance by himself and drove over directly.
Speaking of it, it was unprecedented for Liu Ziang to drive an ambulance to pick up someone.
Of course, in the entire Dongfang Hospital, only Zhao Heng could make a great expert like Liu Ziang drive an ambulance to pick him up in the middle of the night.
Only Zhao Heng has this face.
"That's true. In the traffic situation in Beishi, even at eleven o'clock in the evening, only ambulances are the fastest."
When Liu Ziang said this, Zhao Heng thought about it, and it seemed to be true. I have to say that Liu Ziang is quite reliable. Zhao Heng never thought that Liu Ziang had such a delicate side.
"Senior, you are still quite thin."
After a pause, Zhao Heng sighed again.
"Is this the prepared carbon nanotube? I have only seen pictures in the literature before. This is the first time I have seen this real thing."
Liu Ziang stared at the silver-white metal box with the biohazard icon printed on the surface in Zhao Heng's hand, and couldn't help but sighed a little, what Zhao Heng is holding in his hand now can be said to be the highest achievement in the domestic medical field.
This junior can make big noises every time, which makes Liu Ziang, who has always been very high-profile, have to accept it!
"Actually, it's not that mysterious. Maybe in a few years, nanotherapy will become a routine treatment method in large hospitals."
Zhao Heng said calmly.
The development of each technology will actually go through such a process, from the initial small-scale trial to the subsequent large-scale rollout, this is a necessary process.
However, this time, Zhao Heng used nano-therapy for the treatment of patients, which will still cause a certain sensation in the industry.
After all, everyone is at a stage where they have never heard of nanotherapy, which can be said to be very cutting-edge and high-end, and must be very curious.
And Zhao Heng, a small ward, might become famous in the industry by then.
"It's been a few years. Now this nanotherapy is a rare item. Just say that the box in your hand is definitely the only carbon nanotube that has been put into actual clinical use in Beishi and even the whole country. Junior, this satellite of yours is really big enough."
Liu Ziang said a little astonishingly, even though he is a rare genius and the undisputed master of brain surgery, he has to admit now that he is still a bit inferior to Zhao Heng in terms of innovation.
At this moment, he really didn't know how Zhao Heng's brain grew, and how he could come up with so many unconstrained and effective treatment methods?
Maybe this person is really different from person to person!
"Why don't you come and carry it, senior?"
Seeing Liu Ziang's envious expression, Zhao Heng couldn't help but handed him the box and said.
"Uh... Junior, you are treating me like a kindergarten kid, and you are still carrying me..."
Liu Ziang looked at Zhao Heng speechlessly, however, a mysterious force drove him to take the metal box from Zhao Heng's hand involuntarily.
Really fragrant!
After all, it is a nanomaterial that has been put into use in the field of parasite treatment!
It's good to pick it up and get a taste of the breath of all things.
At this moment, Liu Ziang couldn't help thinking of something metaphysical.
Seeing that Liu Ziang said no, but took the box immediately in action, Zhao Heng also smiled.
After getting into the car, Zhao Heng sat in the co-pilot, and Liu Ziang put the suitcase in the back seat.
"Student, you are tired all night, take a rest first, let me be your driver for a while today. I dare say, I, Liu Ziang, will be the driver. No one in this Dongfang Hospital has ever experienced such a thing. Treatment. How about it, the senior treats you well."
Liu Ziang smiled and said to Zhao Heng.
"Well, I'll trouble you then, senior."
Zhao Heng nodded. Since the morning, he has been working at a high intensity. Although he is fine physically, he is still a little tired mentally. At this time, he really needs to take a break.
Zhao Heng lay on the co-pilot seat, fastened his seat belt, leaned his head against the seat, and closed his eyes. This day was really too thrilling. What Zhao Heng experienced this day may be as thrilling as Ordinary people have experienced it for months, or even years.
It was in this kind of high-intensity experience that Zhao Heng honed his heart to be extremely strong. It can be said that apart from the destruction of the world, there is nothing that can hit Zhao Heng.
This ambulance was really fast. In less than half an hour, Liu Ziang drove the ambulance to the door of the outpatient hall of Dongfang Hospital.
"arrive?"
In a daze, Zhao Heng felt the car stop, so he opened his eyes and asked Liu Ziang.
"Well, here we are."
Liu Ziang nodded.
"11:30? Senior, it's only half an hour, and you're here?"
Zhao Heng looked at the time. It was 11:30. It was eleven o'clock just now. That is to say, even if the road is clear, it would take an hour to drive. Liu Ziang will arrive here in half an hour.
"Don't worry, the matter is special, and it has been reported to the transportation department."
As if knowing what Zhao Heng was thinking, Liu Ziang said with a smile.
"Get out of the car, the dean and the others are waiting."
After a pause, Liu Ziang said again.
"Ah."
Zhao Heng nodded, tidied his clothes a little, and got down from the co-pilot of the ambulance carrying the metal box containing carbon nanotubes.
This feeling is like the returning soldiers facing the welcoming team.
It can be said that this feeling of high-profile is very wonderful, no young man would not like this feeling.
After getting off the car, Zhao Heng saw the dean, Gao Jun, and two vice deans standing at the door waiting, and there were a few middle-aged people Zhao Heng didn't know, who looked like they came from the ministry .
