Huang Junjie came to the genetic testing institute.
Because the genetically modified detector he explained before has been successfully developed.
The head of the institute and researchers are introducing the genetically modified detector to Huang Haojie.
There are two types of detectors they developed, one is handheld and the other is desktop.
Handheld detectors are very similar to smartphones.
Boss, look, this is the handheld detector we developed. The person in charge of the research institute gave one of the handheld detectors to Huang Haojie.
After taking it and looking at it for a while, he figured out how to use it. The handheld detector consists of two parts, the main body of the detector, which is very similar to a smartphone, and the detection sensor head.
The detection sensor head looks a bit like a stethoscope or a magnifying glass.
Boss, the detection sensor head is a lens-like thing, which is the detection screen lens. It is composed of a graphene screen circuit. As long as you gently apply the juice of the crops on it, the detector can detect the genes of the crops in about 53 seconds.
It was detected. The person in charge of the research institute quickly introduced it.
The technical principle of this detection technology is based on the fact that each base is affecting the electronic structure of graphene in a different way, and this can be measured.
Combining graphene-based electronic sensors with nanopores.
By letting a single DNA molecule pass through the graphene electronic sensor, it is like a string of beads passing through a small wire to achieve real-time high-throughput single-molecule sequencing.
A graphene field-effect transistor is used as a probe to reveal the presence of DNA bases adsorbed on the graphene surface.
The Institute of Genetic Testing has proven through experiments that the probe can measure different conductance characteristics after adsorbing four different DNA bases.
This result is attributed to the formation of the interface dipole field.
The tested data will be compared with the database genes in the detector, and the results can be obtained almost in the blink of an eye.
Bring some genetically modified crops and non-genetically modified crops and give them a try. Huang Haojie ordered.
The boss waited for a moment and made arrangements immediately. The person in charge of the research institute quickly went to give orders.
Soon five groups of genetically modified crops and non-genetically modified crops were brought over.
They are large tomatoes and cherry tomatoes, corn, soybeans, papaya and cotton leaves.
Huang Junjie put on his gloves, grabbed the experimental knife on the side, gently cut open the big tomato, took out a little pulp and smeared it on the mirror surface.
Press the detection switch.
Didi
There are some more professional terms at the back.
Huang Haojie asked the person in charge how to remove the residue from the last test.
This issue is very important. If the residue from the last inspection cannot be removed, you will inevitably think about the results of the next inspection.
If you can’t detect it once, just replace the mirror probe! If you do this, the cost will be unacceptable to Galaxy Technology.
Boss, we have already considered this issue. Let’s wash off the residue first. The person in charge said as he put the mirror probe into clean water to clean it.
Then wipe the mirror probe clean.
After washing and wiping off the water, click this ionization cleaning button to remove the residue on the mirror surface.
After speaking, the person in charge pressed a cleanup option on the detector screen.
Huang Junjie nodded and continued to pick up the cherry tomatoes for testing.
Sure enough, cherry tomatoes are shown to be non-GMO. In fact, everyone has some misunderstandings about cherry tomatoes (small tomatoes).
Because many people think cherry tomatoes are genetically modified crops, in fact they are not.
The reason is very simple, because the native species of tomato in its origin in South America is small tomato.
Our common large tomatoes are actually varieties produced through artificial hybridization and selection, and genetically modified tomatoes are also large tomatoes (storage-stable).
Other crops are also tested one by one. The detector is very accurate in detecting genetically modified and non-genetically modified crops.
Huang Junjie thought for a while and asked: By the way, if the crop that needs to be tested is rice or some manufactured products, how should we solve it?
We have also considered this aspect, so we use a comprehensive detection machine. Of course, it is difficult to detect finished products because many finished products are thermally processed, so the DNA or protease is destroyed.
The person in charge pointed to the inspection machine nearby. This inspection machine looked very similar to the previous arcade game machine.
For people who don’t know, they think that Galaxy Technology has launched an arcade game console.
This comprehensive testing machine combines a variety of testing technologies, and it can also detect 100% of semi-finished products such as rice or flour.
Okay, now that the technology is out, you should contact Jianhua as soon as possible to prepare for mass production.
The person in charge of the research institute was overjoyed. After all, putting it into mass production means that their research institute can get a profit of 20% in patent fees.
Yes, boss, I will contact Mr. Li later.
Now that the genetically modified detection technology has matured, your next step can be to research and develop disease genes and gene matching. Huang Haojie suggested.
Okay! We will definitely continue to work hard. The person in charge is like a chicken pecking at rice.
Huang Haojie is thinking about the issue of genetic testing in China. In fact, domestic genetic testing-related projects have been suspended since 2014.
The main reason is because there are no industry standards and lack of supervision.
To give an inappropriate example, the genetic testing companies that are now popping up all over the country are like small restaurants, and the dishes they cook are all called braised pork.
But because there is no supervision, some use chicken as pork, some use tofu as pork, and some even use corrugated paper as pork.
Propaganda A: Our braised pork will make you live forever, only 998.
Propaganda B: Our braised pork can travel through time and space for only 9998. Propaganda D: Our braised pork has its own protagonist halo. After eating it, it can travel across the universe and become invincible for only 99999998.
But you must know that genetic testing is not just about being deceived after eating braised pork. At worst, it will cause you to have a stomachache.
Genetic testing is used to guide medical plans, and abortion and mastectomy are not trivial matters.
If this thing is not allowed to do a prenatal genetic test and tell you that the child has Down syndrome, then abort it. After the abortion, you can check whether the healthy fat boy is okay. Guess how many doctors the child's family will kill.
In terms of industry, for obvious reasons, the big bosses are now more eager to make profits.
In the initial stage of the industry, where genetic testing technology itself is not very mature, bad money has begun to chase good money, and serious business can basically not beat false propaganda.
There are endless false propagandas of all kinds, and as consumers, ordinary people basically do not have enough relevant knowledge to make judgments.
And the huge profits here are not enough for outsiders to understand.
And in terms of technology.
Except for a few clear disease-causing genes, most mechanisms are actually still unclear; most studies on the pathogenicity of gene mutations are focused on Westerners, and the actual impact on Asians is unclear;
Gene sequencing is not the difficulty, but big data processing is the difficulty.
Therefore, the domestic genetic testing industry is in chaos. Most companies are using high-tech guise to cheat money, and a few actually valuable testing projects need supervision.
Genetic testing is an irreversible wave of technology that changes life, but now there is no unified standard in the industry. In a mixed situation, higher authorities have to intervene.
Galaxy Technology is bound to enter the genetic testing industry.
Your Genetic Testing Research Institute is divided into two research institutes, one specializing in gene banks and the other specializing in human genetic research. Huang Haojie thought for a while and ordered.
Okay! I will definitely do it. The person in charge quickly agreed.
