More than ten hours later, Chen Chen stood outside the door of the X-ray radiation room of the institute, flipping through the X-ray films in his hands.
Most of the X-rays are blank, and some have only a tiny dot on them, which can be ignored inadvertently.
These X-ray films are what STEM chips look like under X-rays.
The so-called X-ray is actually a kind of electromagnetic radiation, but its wave band covers a wide range from 0.001nm to 10nm. It is located between ultraviolet rays and Y-rays in the electromagnetic spectrum, and the corresponding energy range is from 125eV to 125keV.
People engaged in similar professional fields often refer to X-rays with wavelengths between 0.001nm and 0.1nm as hard X-rays, and those with wavelengths above 0.1nm as soft X-rays.
According to the data ratio of X-rays penetrating carbon elements, soft X-rays with a wavelength of about 0.2nm or above can illuminate diamond-like substances with a thickness of more than 3mm, and the core processor of STEM is a diamond-like crystal with a diameter of 3mm.
The X-rays used in security inspections are still soft X-rays with lower energy. Therefore, in principle, the chip is visible after being implanted in the human body.
However, to Chen Chen's surprise, the mainboard material of the STEM chip is a special biocompatible substance that has compatibility with the human body.
In other words, even if a person with a chip implanted takes an X-ray, it can only reveal the core processor of the chip, but it will be difficult to find traces of the chip's motherboard.
Moreover, the core processor of the chip is as big as a sesame seed, so it is almost invisible unless you are looking for it.
It is indeed a high-tech chip of the future, and it has even thought of this.
Chen Chen secretly sighed, but this in turn gave him an advantage. Even if he went through airplane security or even a hospital X-ray examination, the concealment of the chip could be guaranteed to a certain extent.
"It's time to build your own team..."
Chen Chen murmured in a low voice, then destroyed all the X-ray films, turned around and left the room.
…
"Mr. Samuel—"
In the evening, when the researchers were about to get off work, Samuel, who was checking the equipment, was stopped by Chen Chen.
"Please come to the main control room later. I have something to discuss with you."
"As you wish."
Samuel glanced at Chen Chen inexplicably, and then nodded.
Returning to the main control room, Chen Chen slowly poured two cups of cappuccino and placed them in front of the table. Then he picked up a paper document on the table and read it with relish.
About ten minutes later, there was a knock on the door of the main control room.
"Please come in." Chen Chen raised his head slightly, and Samuel immediately pushed open the heavy iron door and strode in.
"Boss, you..."
Just as Samuel was about to ask something, Chen Chen shook his head and pointed at the hand on the table to make coffee, "Write it while it's hot. It will be cold later."
"… Thanks."
Helpless, Samuel had no choice but to sit down opposite Chen Chen.
Snap!
Snap!
snap…
Rhythmic knocking sounds were heard. Samuel heard the sound and looked around, but it was Chen Chen who was tapping the table with his index finger, and his eyes never left the document in his hand.
Um, files
Samuel suddenly looked familiar. Looking at it from his side, he saw that a section of the document was exactly...
"boom!"
After seeing the contents of the document clearly, Samuel suddenly slapped the table hard, and the coffee spilled directly on the table, "Boss, what do you mean?"
"What do you mean?" Chen Chen put down the document.
"I mean the file you saw!" The anger in Samuel's eyes almost burned, "Why is my file here with you? What do you want to do to me?"
"Take it easy."
Chen Chen took a sip of his coffee and said slowly, "There is a reason why I did this. Before you get angry, please listen to my explanation, okay?"
"For whatever reason, this national file should not be on your desktop!"
Even so, Samuel took a deep breath to suppress the anger in his heart and waited for Chen Chen's explanation.
"Mr. Samuel, you were born in 1975. You are 46 years old this year. You married a Polish woman in 2003 and had a daughter after your marriage."
Chen Chen read while reading, "However, just ten years ago, on your daughter's seventh birthday, a car accident caused her spine to break, resulting in paralysis of both legs."
"So, what do you want to express?" Samuel said, suppressing his anger.
"As far as I know, you were once a medical doctor?"
Chen Chenruo pointed out, "But after your daughter became permanently disabled, you changed careers and started studying the field of stem cells. I wonder why?"
"Isn't this obvious?" Samuel threw the question directly.
"Is it because you want to save your daughter through your own efforts?" Chen Chen asked, "But when I first met you, you didn't seem to be doing this."
"..." After hearing this, Samuel fell silent.
After a long time, he sighed and said, "Yes, I have been studying the field of stem cells for ten years and have been waiting for ten years."
"As for the level of modern medicine, only the field of stem cells gave me a glimmer of hope, so I gave up my favorite clinical medicine and turned to stem cell research."
"It's just that I thought I could find a way to treat Annie with my talent. But it wasn't until I really entered this field that I realized how ridiculous my confidence was..."
"So, you are waiting?" Chen Chen asked.
"Yes, I can only wait, waiting for stem cells or some other field to be able to cure spinal cord injuries, but I have never waited for so many years."
"I don't know how many more years to wait. My daughter is already seventeen years old. While her peers are still enjoying their youth, she can only sit in a wheelchair and look at them with envy..."
Samuel held his head and cried softly, "I am not a qualified father..."
"You are too self-indulgent, Mr. Samuel."
Chen Chen sat opposite, still expressionless when Samuel revealed his true feelings, "Your academic level in the field of stem cells may not be the best in the world, not even second-tier, but there is still something remarkable about it. .”
"How about this… "
As Chen Chen said, he took out another paper document and placed it in front of the other party, "If you can sign this agreement, I may be able to help you fulfill your wish."
"You?" Samuel's heart moved.
He used to be so domineering that even the company's shareholders looked down upon him. However, as Chen Chen showed his talent, his attitude changed 180 degrees. This change had puzzled many people.
But only Samuel himself knew that the reason was simply that he pinned his wish for his daughter's recovery on Chen Chen.
Although it was very slim, as long as Chen Chen could develop a stem cell method to repair spinal injuries, his daughter would have hope of recovery.
