Force To See The Future, AI Help "Post Epidemic Era"

From the beginning of the new crown pneumonia epidemic, the research and development project for the detection of new crown virus has been carried out nervously and without interruption.

In May 26th, the Tsinghua University School of pharmacy Bai Jing Wei, Li Yinqing and the Medical Research Institute of Biomedical Engineering Liu Peng research group developed an integrated self-service SARS-CoV-2 nucleic acid detection cassette (BINAS), which has the convenience of home detection, and can be detected within 30 minutes. In addition, Jiangxi University Donghua Polytechnic University research team has developed a new crown pneumonia detection technology, 3 minutes to complete a single sample detection.

Zhang Sheng, a researcher at the Ningbo Research Institute of Zhejiang University, said in an interview with the twenty-first Century economic report reporter that the school is also using mobile phone portability for research and development, combined with the current nucleic acid detection technology to rebuild the mobile phone and detect the new crown virus, and it can produce results in a few minutes, with the advantages of speed, time saving and convenience.

Looking back over the past six months, the demand for detection from the beginning of the epidemic is very urgent. Up to now, 1 million 500 thousand nucleic acid tests have been carried out every day, and industrial applications are being speeded up. It takes at least 4 hours to start from the beginning, and to the current level of 1.5 hours, technology is also making progress.

In fact, the research and development achievements of the scientific research field are not only aimed at the new crown virus, but also play a great role in the detection of similar influenza viruses in the future. It is a basic principle for researchers to make use of the target of virus to make chemical probes for virus detection, but in the non laboratory scenario, there are still many uncertainties.

AI combined with big data

After the outbreak of the new crown pneumonia, the joint defense and joint control mechanism of the State Council set up a scientific research team led by the Ministry of science and technology and participated by 12 departments. The scientific research group set up an expert group composed of academicians Zhong Nanshan and 14 experts.

During the two sessions, Cheng Jing, a member of the National People's Congress and academician of the Chinese Academy of engineering, told the media that the research work of the vehicle new crown virus detection laboratory is speeding up. Some of them have been completed. It is expected to come out at the end of June, and can be put into operation as soon as possible in July. According to the preliminary test, the test can complete nucleic acid detection within fifty minutes. Because it is vehicle mounted, flexible, such as community outbreaks of mass outbreaks, sampling and testing vehicles carrying test laboratories can reduce the risk of further transmission of viruses caused by human mobility.

Cheng Jing also showed the latest fully integrated detection chip on line. "Our R & D has been going on and never stopped. The half integrated detection chip developed before will take 1.5 hours to produce results. Now the newly developed fully integrated detection chip can produce the test results in forty or fifty minutes.

He suggested that in order to deal with the new and outbreaks of major infectious diseases that may occur again in the future, it is recommended to build an automatic monitoring and reporting system from the provincial, city and county coverage. Through the combination of new pathogen detection technology and 5G communication, big data and artificial intelligence technology, a network, real-time and automatic epidemic surveillance and reporting system will be realized, and a full coverage of intelligent epidemic will be formed. Monitoring system.

It is reported that the technical level and product performance of our testing reagents are at the same level as those of developed countries, and the capacity of testing products and current detection capabilities basically meet the current needs.

Landing still takes time.

In May 18th, on the day of the opening of the seventy-third World Health Assembly, a new crown virus antibody test kit came from Japan. Not long ago, the Ministry of health of Malaysia also issued a similar evaluation news.

Since the outbreak of the epidemic, the world has been accelerating R & D, and time is life. However, it will take time for new crown to detect the achievements of various technologies. The research achievements of Donghua science and Engineering University research team also need examination and approval to put into specific locations. The R & D project of the Ningbo Research Institute of Zhejiang University is also in the stage of technology research and testing.

"At present, we are developing the detection case for mobile phones, and the chemical probes are also being developed." Zhang Sheng further revealed that after the completion of laboratory experiments, the biggest difficulty is landing and research and testing in non laboratory environment. Because the non laboratory environment is uncontrollable, testing in the laboratory may be perfect, but in the non laboratory environment, the accuracy of the test may be greatly reduced, thus affecting the actual use effect, causing errors.

In addition, a technology itself may be successful, but when its cost is too high, and it is not suitable for large-scale and universal testing environment, it still faces the risk of being eliminated.

In the future, on the basis of ensuring the accuracy of detection results, it is necessary to further reduce the detection cost. The reduction of cost means the expansion of the scope of detection technology.

The mutation of the virus itself has brought great difficulty to scientific research. "In fact, we are exposed to many viruses. Many samples may have different mutations in special location points. So it is not yet clear how many viruses are mutable. Another researcher told the twenty-first Century business reporter.

The trend of the new crown pneumonia epidemic has not been completely suppressed worldwide, and the parties are still making unremitting efforts. Recently, Seagate, the world's largest mechanical hard disk company, announced that it had signed the Open COVID initiative, which could freely authorize Seagate's all technology patents for the identification, detection, prevention and treatment of the new crown virus. A recruitment information in Amazon also revealed the commitment of technology companies to invest in R & D, and is responsible for developing the hardware department of the company's Kindle e-reader and Echo smart speakers. Amazon's secret lab Lab126 is recruiting engineers to carry out the detection of new crown virus.

The ultimate goal of the global electricity giant is to build a testing network that is covered by a powerful central testing center, which is aimed at helping build the network. In the future, the power of science and technology will play a decisive role in epidemic prevention and control.
