Chapter 105 Air Detection

But when Chi Heng thought about it carefully, he found it unbelievable. This is not a cartoon. Cartoons will anthropomorphize animals to attract children. But if such creatures really exist in reality, cute is cute. Imagine it for real. Creepy.

Chi Heng stared at "Hedgehog Leopard" and pondered for a moment, until "Broken Copper and Iron" asked: "Sir, what should we do next?"

"You ask me how to deal with it?"

Chi Heng pondered: "Do you think this thing can speak human language?"

"Junk doesn't know either."

"Broken copper and iron" suggested: "But you can take a CT scan for it and collect some blood samples for analysis."

"When you say that..."

Chi Heng nodded with great interest, "Let's see first, after it wakes up, try feeding it some sleeping pills."

Sleeping pills mainly refer to benzodiazepines, which stimulate the GABAA receptors, thereby reducing the firing of neurons and inhibiting the central nervous system.

Generally speaking, mammals are affected by sleeping pills, but what about this abnormal natural creature?
What if it doesn't have GABAA receptors?
That sleeping pill certainly wouldn't do it any favors.

Chi Heng checked the time, because he woke up very early, it was only 9:35 in the morning, so there was plenty of time.

He took out some chocolates to supplement the energy consumed by his body. He was a little worried that the "old man" would wait anxiously. While thinking about it, the "hedgehog and leopard" who had been unconscious before suddenly woke up, baring his teeth and growling in a low voice. I struggled hard, but unfortunately I was trapped in the glass box and couldn't move my hands and feet.

"Wake up."

Chi Heng didn't get too close, let the "broken copper and iron" stand in front of him, poked his head out from the robot's shoulder, stared at the "hedgehog and leopard", first asked in English, and then greeted in Chinese, but they didn't attract any attention. Come to the answer of "Hedgehog Leopard", it just bared its teeth at Chi Heng like a cat.

Chi Heng was keenly aware that its teeth were not densely arranged in the shape of a "mountain" like cats. They were composed of molars, cleft teeth, incisors, and canines, which could easily tear and divide meat. Its teeth were arranged like humans. But the shape is very similar to canine teeth, and there are molars that can grind food.

This shows that this "hedgehog leopard" has both the physiological characteristics of cats and human physiological characteristics, which can be regarded as a combination of the two.

The doubt is that its intelligence does not seem to reach the level of human intelligence.

But it cannot be directly denied, because at this time the "Hedgehog Leopard" was obviously under stress and was in a state of high emotional tension. It believed that Chi Heng and "broken copper and iron" had threatened it, and it was impossible to proceed at this time. communicative.

Chi Heng temporarily gave up the plan to communicate, he signaled "broken copper and iron" to push the glass box aside, and asked, "Can this fluidized food maker still work?"

"Broken copper and rotten iron" had checked it before, and now he shook his head when he heard the words: "It has been damaged and cannot be started."

"That's a bit of a hassle."

Chi Heng thought for a while and took out a piece of chocolate: "I don't know if it can be eaten? Forget it, chocolate may cause animal allergies."

He changed it to biscuits, added some water, made a paste, mixed sleeping pills into it, and let "Broken Copper and Iron" print a very long spoon, um, have you seen a spoon that is more than one meter long?

Then he poured the paste into the spoon, and he handed it over with the spoon in his hand from a distance.

The "hedgehog and leopard" keeps baring its teeth, with a fluffy child's face, even baring its teeth is quite interesting.

It had no intention of eating the food in the spoon at all, and stared at Chi Heng fiercely.

"It seems that it didn't appreciate my kindness."

Chi Heng sighed: "This is a long battle."

Putting the spoon down, the one thing that Chi Heng must do now is to let the "bad copper and iron" go to the P1 biological laboratory to check the virus in the air.

Originally, he thought that he came in wearing a biological protective suit because the core area was very dangerous, but after entering, he realized that the danger is danger, but the danger lies in the high-level independent laboratory, which cannot be entered, so what is the danger?
Of course, just in case, Chi Heng still needs to detect whether there are special viruses in the air... For example, whether a system composed of tiny aerosol particles (viruses, bacteria, fungi, animal and plant-derived proteins and other microorganisms) will threaten to him.

Wearing this set of biological protective clothing is too troublesome. If possible, Chi Heng wanted to take it off. When he rolled on the ground to dodge before, it was because of this protective clothing that he almost lost his waist.

Leaving the "hedgehog and leopard" who couldn't move here, Chi Heng and "broken copper and iron" went to the P1 biological laboratory. On the bioaerosol collector printed by a 3D printer, there is a specially designed cavity in the middle of the collector, in which the air inhaled by the air inlet will form a vortex, and the flow rate of more than 600 liters per minute is enough to dissipate the aerosol in the air. Particles such as aerosols are thrown into the inactivation solution in the collection tube.

For the sake of accuracy, Chi Heng and "Broken Copper and Iron" acted separately, of course not too far apart, and collected bioaerosols in many places, especially at the entrance of the two P4 laboratories.

Next, it is operated by "broken copper and iron", and uses a pipette gun to take out 1 ml of the sample liquid in the collection tube, transfer it into the sample tube, and then put it into the cartridge, and start the test as if it is fully closed.

Chi Heng immediately realized the advancement of the biological laboratory here. Even the lowest level of P1 laboratory has more equipment than the earth where he is.

The United States has the most advanced biotechnology in the world, but it can't be like it is now, except for the need for pool scales and "broken copper and iron" to collect samples, and the rest of the fully automated processing.

After the cartridge is put into the detector, it will automatically capture samples such as viruses and bacteria in the sample. For example, the nucleic acid of the virus will be lysed, and then the reaction reagent will be used for local in situ amplification, and finally read by the fluorescence detector, corresponding to the sample library The data in the test result can be generated.

And this whole process does not require manual participation, and the detection sensitivity has reached 5 copies per milliliter.

What is this concept?
If the conventional fluorescent quantitative PCR method is used for detection, it needs more than 500 viruses per milliliter to detect it, but using the equipment here, the sensitivity can reach 5 viruses per milliliter, which is the current conventional method on the earth where Chi Heng is located. 100 times! (Earth is now 2005)
Soon, in half an hour, all the sample test results came out.

Chi Heng couldn't understand the test results, but it didn't prevent the "bad copper and iron" from understanding it.

It browsed through it and told Chi Heng the answer directly. The air here is very pure, beyond ordinary purity. It definitely adopts an ultra-high-efficiency air purification and filtration system, and the cleanliness is above ISO Class1.

"That means, it's okay for me to breathe the air here directly?"

"Sir, if the air here cannot be breathed directly, then there is no place on earth where you can breathe freely."
