Chapter 643 This is not a virus
The disease research institute has received many patients transferred from all over the country, including those in stages 1, 2, and 3.
Lin Xiaohe, wearing thick protective clothing, entered a ward.
The ward walls were painted light pink, and a bunch of pink carnations, covered with a transparent dome, sat on the coffee table next to the bed, adding a touch of warmth to the ward.
There were two beds in the ward, one in a coma and the other chuckling foolishly.
"The sun shines brightly, the flowers smile at me, the little birds get up early, and carry their explosives. Boom!"
The woman on the hospital bed looked worried and had tears in her eyes, but she clapped her hands happily and sang a particularly cheerful song.
The nurse following behind Lin Xiaohe whispered to her, "The patient, Wang Shuxiang, is extremely resistant to injections. We have tried many times, but we have been unable to get her to cooperate in drawing cerebrospinal fluid."
If it were any other patient, the medical staff would naturally have other options, but Wang Shuxiang's identity is special; she is Lin Xiaohe's mother.
As soon as she finished speaking, Wang Shuxiang saw the nurse in the white coat and immediately shrank under the covers, only her head sticking out. She put on a bright smile, but her eyes were particularly wary: "You daring devil, what do you want to do to me?"
The nurse stopped and shrugged helplessly.
That's how it is; you can't be too gentle or too harsh, and the patient won't cooperate. What do you do?
Lin Xiaohe stood by Wang Shuxiang's bedside, looking down at her: "Do you remember who I am?"
Wang Shuxiang glanced at her, then lowered her eyes again, and began to sing: "I mistakenly entered the imperial palace, and was advised to put down the sand in my hand, but when I opened my mouth to sing, my voice became hoarse..."
Lin Xiaohe carefully observed Wang Shuxiang's expression, confirming that she was immersed in her own world. She couldn't help but sigh inwardly, and in the blink of an eye, she raised and lowered her hand in a karate chop.
Wang Shuxiang was struck in the neck and collapsed onto the hospital bed like a limp noodle.
Lin Xiaohe: "Give her anesthesia and extract cerebrospinal fluid."
"Ah? Ah, okay." The nurse clicked her tongue in amazement. As expected of Lin Xiaohe, she was decisive and efficient.
Lin Xiaohe left the ward and went back into the laboratory.
The once spacious laboratory is now half occupied by a huge vertical piece of equipment.
It is a TEM transmission electron microscope that was urgently transported by Changhong Group. At its core is a towering, pillar-like upright metal tube, more than two meters high, connected to a complex array of vacuum pipes and cables.
In the lower middle part of the microscope tube, there is a small fluorescent observation window, which emits a faint green light.
The actual operating interface is on the computer control panel next to the microscope tube. There's a small joystick next to it for fine-tuning the sample.
Mr. Yuan and the others stood near the door, at a loss: "Leader Lin... we don't know how to use it. How about you transfer a few technicians from Changhong Group?"
Lin Xiaohe: "It's okay, I know how to do it."
The technicians at Changhong Group all have their own research tasks, and they wish they could split themselves into three pieces, as they simply cannot be in two places at once.
Sampling for TEM is very complex and time-consuming. Its imaging principle requires that the electron beam can penetrate the sample, so the sample needs to be extremely thin, less than 100 nanometers thick.
Lin Xiaohe personally took charge of the operation and spent three hours preparing the sample.
The next task is to move the sample using a trackball similar to a game controller joystick on the control panel, and in conjunction with the magnification knob and focus adjustment knob, continuously search for abnormalities in the cerebrospinal fluid in the field of view.
This work, like scientific research, requires patience, time, and luck.
If you're lucky, you can succeed on your first try.
If we're unlucky, we don't know how long it will take.
Yuan Longping opened his mouth, wanting to ask Lin Xiaohe if there were any special research ceremonies, but seeing Lin Xiaohe's straight back, he didn't dare to speak. With the advantage of home ground and divine blessing, Lin Xiaohe's luck was naturally extremely good.
After observing only two samples, Lin Xiaohe found the culprit.
"Wow, it's not a virus after all."
Everyone's spirits lifted.
Mr. Yuan rushed to the control panel and excitedly asked, "Is it bacteria?"
Lin Xiaohe shook her head and gave up her seat: "No, it's an abnormal particle, similar to an exosome, but smaller, about 30 nanometers."
Lin Xiaohe thought for a moment, then walked out of the laboratory and called the Changhong Group Research Institute: "Send another nanoparticle tracking analyzer."
Yuan Lao licked his lips and asked weakly, "What is this?"
Lin Xiaohe: "It emits a laser beam that shines into the liquid containing the sample. Once these tiny particles are illuminated by the laser, they are captured by a highly sensitive camera. The software then tracks the chaotic, random motion trajectory of each particle."
Everyone...
I can't understand it at all.
They thought that through their hard work over the past two years, they had reached the pinnacle of global technology, but they did not expect that this mountain was not a mountain, and this water was not water.
The pinnacle of global technology lies in the Changhong Group Research Institute, and the pinnacle of the research institute lies in Lin Xiaohe.
Lin Xiaohe explained in plain language: "To give an example, TEM randomly selects several parking lots throughout the process and checks each car one by one with a magnifying glass. Although we can see every detail clearly, we may not be able to find the car we want, and even if we do find it, we can't calculate the total number."
"The nanoparticle tracker has cameras installed at all intersections, which can quickly scan and count how many of these vehicles there are in the whole city."
Everyone nodded in unison.
Although they were still confused and could only understand half of what they heard, they still nodded.
As one of the nation's top research institutes, don't they have any pride?!
Besides, time is life, how could they waste Lin Xiaohe's precious experimental time?
They first memorized Lin Xiaohe's words word by word, and then thought about them slowly when they got back.
The Changhong Group Research Institute has always regarded Lin Xiaohe's needs and instructions as top priority tasks.
Lin Xiaohe only waited for three hours before the special plane from Changhong Group's research institute arrived.
The nanoparticle tracking analyzer is much smaller and more compact than the TEM, with a square shape that makes it look more like a precision instrument placed on a laboratory bench.
Its operation is more intelligent; you only need to open the front cover and insert the sample-carrying stage for automatic detection.
Lin Xiaohe and the others only need to look at the computer monitor next to them. The computer will track these light spots to analyze the size and concentration of the particles.
With precise observations using TEM and nanoparticle analyzers, researchers finally determined that the unknown particles were the cause of the flu.
……
Under a blue sky and white clouds, on the vast, deep blue sea, lies a solitary island.
Several helicopters slowly landed on the island's helipad.
Ground staff immediately stepped forward to greet the guests of Eden.
"Hey, Gingrich. Your inventions and plans will amaze the world!"
"Oh dear, our eccentric president is having a headache over the ever-increasing number of patients in the country. He won't have time for this gathering."
