The rise of nanometers

Night falls.

In the canteen of Shennong Group headquarters.

Liu Xing and Tian Shengwen were eating while listening to the assistant say something.

Although both of them are employees of Shennong Group, there are many laboratories and various sensitive technologies in the headquarters, and they cannot just wander around.

After speaking, the assistant sent a simple guide to the two of them. The guide marked the areas that were inaccessible and the areas that could be visited.

"You two, do you have any application to visit? If so, you can make an appointment in advance so that I can register it for you."

After thinking for a while, Liu Xing replied: "I don't know much about the headquarters. Does Assistant Huang have any recommendations?"

Assistant Huang recommended two areas: "The botanical garden and the medicinal botanical garden are good, and the artificial bone laboratory is also good."

"Then the botanical garden and the artificial bone laboratory!"

Assistant Huang nodded: "No problem, I will help you register later, and I will send you a passcode on Chaoxin."

"Sorry to trouble you!" Liu Xing thanked him.

"You're welcome."

After dinner, the two of them were arranged to the reception dormitory area. Three of the other five hospitals testing AIDS treatment had already come, and their people were also in the reception dormitory.

the next morning.

In the cold wind, Liu Xing and Tian Shengwen were wearing casual clothes. After having breakfast, they received the pass code.

They and several other people from the testing hospital took an electric sightseeing car and headed to the botanical garden.

Although there are many plants at the headquarters of Shennong Group, in fact, the real botanical garden only occupies 24% of the area and requires driving through a tunnel.

When they passed through the tunnel, they came to a valley surrounded by mountains, which was divided into many small areas. 67% of the area was a large glass greenhouse, which contained small ecological botanical gardens simulating various regions, as well as medicinal botanical gardens.

A doctor from Chang'an Shennong Hospital looked at the sign on one of the greenhouses and exclaimed that the headquarters was rich and wealthy: "The Qinling Botanical Garden is also an ecological and climate simulation greenhouse. The headquarters is really willing to give it up!"

"There are also North American Botanical Gardens and South American Botanical Gardens there. Basically, except for Antarctic plants, they are found in other regions."

"The chemical extracts of these plants do have huge potential value. I heard that the Institute of Traditional Chinese Medicine extracted an active ingredient from a polar moss that can inhibit the reproduction of Helicobacter pylori."

Liu Xing has also read relevant papers: "Indeed, human beings' understanding of nature is still too shallow, especially for all kinds of strange creatures. Their bodies are a natural treasure house."

Everyone was chatting and visiting the botanical garden.

All kinds of strange tropical rainforest plants, tenacious polar tundra plants, and drought- and heat-resistant Sahara desert plants can all be seen here.

The environment and time, the genes shaped over hundreds of millions of years, contain the memory of Blue Star and also contain the magic of natural creation.

Huang Xiuyuan asked Shennong Group and Fenmin Agriculture to establish these botanical gardens, zoos, and strategic seed banks in order to protect these genetic resources and to discover the mysteries of life within them.

Although humans have made great progress in genetically modified technology, this is not the capital of human arrogance.

In front of nature, humans are never qualified to be arrogant.

Huang Xiuyuan is eager to know the secrets of genes, but he is also in awe of nature, because he knows that genes really contain too many secrets.

With the current level of human biotechnology, it is far from being able to interpret all the information. In fact, if you look at the history of human science, you will know that many technologies are imperfect.

Perhaps in modern times, this technology is already perfect, but as time goes by and technology develops, if you look back at the previous technology, you will find that there are too many shortcomings.

When it comes to genetic research, Huang Xiuyuan is very opposed to blind radicalism and genetic research led by private companies.

Although the Shennong Group participated in the Nuwa Project and the Fuxi Project, it has always been very cautious and used knives on human genes. If it is too radical, the consequences may be disastrous.

Inside the botanical garden.

Liu Xing and his party walked around for a while, and it was almost noon. They went back to the cafeteria and had lunch.

Taking advantage of lunch break.

He opened his notebook and browsed papers and information.

In the afternoon, they did not continue to the botanical garden, but left the headquarters of Shennong Group and went to Luhe County for sightseeing.

In the sea of ​​plum blossoms that cover the mountains and plains, there are many foreign tourists taking photos under the plum trees.

Liu Xing and Tian Shengwen also took out their mobile phones and took some photos.

The third day.

They were invited into the artificial bone laboratory.

This laboratory is located halfway up the mountain southwest of the headquarters. It has more than fifty related researchers and is a medium-sized laboratory.

Inside the laboratory.

Everyone saw various artificial skeletons.

Tian Shengwen pointed to a row of artificial teeth and said curiously: "Dr. Liu, look at these teeth, they feel exactly like real teeth."

The area they visited was not the core scientific research area of ​​the laboratory, but the product display and testing area.

The intern researcher who led them explained with a smile: "These artificial teeth are actually not much different from real teeth, except that they have no dental nerve."

A visiting doctor who had learned about dentistry asked thoughtfully: "Researcher Yan, are these artificial teeth intended to be used in dental implants?"

Researcher Yan nodded: "Yes, but there are some differences from traditional dental implant technology."

the difference? Liu Xing observed carefully and found that there were no screw holes at the bottom of these artificial teeth, and they were longer than ordinary dental implants.

"You may have noticed that our artificial teeth do not have screw holes. This is because our dental implants do not require drilling and nailing."

The same doctor just now raised a question: "How to connect the artificial teeth to the alveolar bone without drilling nails?"

"This is one of the core projects of our laboratory research, ossification technology, which allows artificial bone and artificial teeth to be perfectly and harmlessly combined with natural bones." Researcher Yan explained.

This ossification technology is the core of the supporting technology for artificial teeth. After all, artificial teeth are relatively simple. Using 3D printing technology similar to powder metallurgy, safe and harmless artificial teeth can be quickly produced.

But artificial teeth are not the key. The key is how to implant teeth. The traditional dental implant technology is to drive a titanium alloy screw into the alveolar bone and then put on the artificial braces.

This process not only requires the dentist's technical skills, but also requires consideration of many issues, and the cost is relatively high. Usually, a dental implant costs about 8,000 to 15,000 yuan.

Although the price of imported dental implants has dropped by 30 to 40% due to the appreciation of the Chinese yuan in the past two years, the price is still relatively high.

Partly because the price of imported dental implants is relatively high, and partly because dental implants require professional dentists and the implantation process is complicated.

In order to reduce the cost of dental implants, the Artificial Bone Laboratory has developed osseous bonding technology to make dental implants safer and cheaper.

This technology can measure the depth of the alveolar bone, inject a nanoparticle into the alveolar bone and the artificial tooth, then fix the artificial tooth in the alveolar, and finally inject a catalyst that can prompt the nanoparticles to react. Then the artificial teeth and alveolar bone are tightly combined.

As long as there are supporting equipment and raw materials, ordinary dentists can operate it.
