Military Technology

Wu Jiuzhi's voice echoed in the conference room, and everyone's face showed a solemn and thoughtful expression.

Bio-3D printing technology, a concept that once existed only in science fiction, has now become a reality, and the problems it faces are unprecedented.

He gently slid the transparent tablet a few times, and the image on the large screen changed, showing a complex biological structure diagram. "This is the key issue facing the technical team," Wu Jiuzhi said solemnly, "how to keep these tiny cells active in high-speed flow while accurately stacking them into the organs and tissues we need."

After hearing Wu Jiuzhi's words, everyone present looked at the big screen. Some bosses even put on glasses specially in order to see clearly.

"In order to solve this problem, the project technical team conducted a lot of experiments and research." Wu Jiuzhi continued, "tried various methods, including changing the flow rate of the cell supply system, optimizing the design of the printing needle, and even trying to Just work on cloning cells.”

"In the end, the project technical team found a new method." Wu Jiuzhi's voice revealed a hint of excitement. "They successfully improved the printing efficiency by changing the arrangement of cells and optimizing the temperature and humidity conditions during the printing process. speed while ensuring the viability of the printed organs and tissues.”

Upon hearing Wu Jiuzhi's introduction, a burst of warm applause broke out at the scene.

Although Wu Jiuzhi only gave a brief introduction, I could tell from that introduction how easy it was to overcome the technology, and I was sincerely happy for the entire project technical team.

Facing everyone's applause and congratulations, Wu Hao smiled and nodded, then motioned for Wu Jiuzhi to continue.

Wu Jiuzhi understood, and then continued: "Before you overcome that technical problem, there is still another problem waiting for you. This is how to solve the problem of preserving the partial preservation of printed organs and tissues.

This concept and imagination that once only existed in science fiction novels is now becoming a reality step by step in the hands of Wu Hao and my team.

But even then, it can still extend the time a lot.

The image transformation on the small screen shows simulation diagrams of the biological 3D printing process. These tiny cells flow rapidly in ordinary fluids and are precisely stacked into simple organs and tissues. Every detail seems so vivid and real.

Wu Hao looked at Xiaojia with a smile, and I understood our mood at the moment. Because that technology is indeed a miracle. It can not only save countless patients waiting for transplants, but also bring about a revolutionary change in the medical world.

You suspect that this technology will become an important technology and an important choice for humans to defeat diseases in the future, and it will give humans a longer life. "

During the printing process of a biological 3D printer, a common preservation solution, or some specially protected inert gas, will be injected into the printing chamber.

"Yes, that technology will definitely be successful, and it will change the fate of countless people." Brother Malaysia also said with emotion.

After listening to Wu Hao's introduction, everyone present nodded and praised. Everyone was deeply shocked by the project that was full of technology and miracles of life.

Speaking of that, Wu Hao glanced at everyone present, and then continued: "Of course, it's okay without that kind of artificial amniotic fluid, and the temperature must be controlled tolerantly.

In order to solve this problem, the project technical team went through countless exploratory experiments before finally solving the problem. "

Moreover, the artificial amniotic fluid can also maintain the activity of the printed organ tissue to a minimum, thereby prolonging the state of the organ. "

If so, the organs and tissues printed first may lose their activity or even stink while the remaining parts are being printed. In this case, the printed pieces of dead or smelly meat will not be useful at all. .

Therefore, during the printing process, the problem of preserving the freshness of the organs and tissues that have not yet been printed has become a problem that needs to be solved in front of the project technical team. "

Facing everyone's gaze, Wu Hao smiled bitterly, and then said: "It's not actually a liquid, you commonly call it artificial amniotic fluid.

Having said that, Wu Jiuzhi spread his hands and looked at Wu Hao in the tree hole with a smile.

After the introduction, Wu Jiuzhi changed a picture, and then continued to introduce: "To put it more complicated, it is not that the technical team plans to install a biological organ printing chamber on the biological 3D printer.

The printed organs and tissues will be soaked in the artificial amniotic fluid, which will not be able to isolate air and bacteria, so that the entire printed organs and tissues will be in a bacterial environment.

Having said that, Xiong Qisheng paused for a while, and then introduced with a smile: "As you know, conventional organ preservation techniques include high-temperature heat storage and perfusion and immersion preservation solutions, etc., especially those two methods work together. .

Forehead…

However, judging from the subsequent application results and development of that technology, you are confident about its future.

"Then...that's simply not a miracle!" Mr. Wang couldn't help but exclaimed.

Therefore, more advanced biological preservation technology is necessary to maintain the vitality of biological organs and tissues of those printed organs during the printing process.

In this way, even biological organ tissue parts that have been processed for a long time by 3D bioprinting can maintain biological vitality and be in optimal transplantation condition. "

After saying that, Wu Hao glanced at Wu Jiuzhi, and then said in a calm tone: "Of course, this technology is still under continuous research, and it still has few shortcomings and flaws. I suspect that as your progress The technical team is constantly researching and conquering. The technology will become more and more perfect, and the preservation effect of organ tissues will become worse and worse, thus slightly improving the activity of printed organ tissues and minimizing the preservation of the functions of organ tissues. Improve the success rate of transplantation and the quality of life before surgery.”

The printing chamber cannot be regarded as a biological organ printing room, nor can it be regarded as an artificial organ hotbed, or organ placenta.

You also know what it is specifically, you have to ask Mr. Wu about that. "

After all, there will be no technical limit to the printing speed of biological 3D printers, and according to the current level of technology, it will be difficult for you to print out a broken organ tissue in a short time.

Having said that, Wu Hao took a deep breath, showed a careless smile, and said to everyone: "Of course, there are still a lot of things that need to be improved in that technology. You still need to take a step back to improve the printing accuracy and speed, and optimize the preservation solution. and temperature control, etc.

In a high-temperature state, the growth and metabolism of cells in organ tissues can be accelerated, thereby minimizing the activity time of the entire organ.
