Head map source | pexels Raising public health awareness and the implementation of the Food Safety Law have made food safety a hot topic in recent years.Due to the time-consuming and high cost of traditional food detection methods, in recent years, a molecular structure analysis method based on the Raman scattering principle has gradually emerged.This principle means that when light interacts with a molecule and a few photons undergo inelastic scattering, the energy of these few photons will be partially transferred to the molecule, causing the frequency shift of the scattered light.When the displacement occurs, the vibration mode information based on the chemical molecular bond will also change. This change will be reflected on the Raman spectrum through the position, number and band intensity of the spectral line. The content of different substances in the test product (such as harmful substances, restrictionsAdditives, etc.) will be distinguished.In the field of food safety testing, Raman spectroscopy technology is mainly used in Raman spectrometers.Nano-probes and chips are one of the core components of this type of intelligent food safety testing instrument.How to improve mass production efficiency, reduce costs, and improve detection accuracy and ease of operation is an important direction for the development of such core component suppliers.36 氪 Recently observed that “Guangxi Sanhuan High-Kuraman Chip Technology Co., Ltd.” (hereinafter referred to as “Three-ring Raman Chip”), which was established in September 2019, mainly develops, produces and sells surface-enhanced Raman for core components.Nano-ceramic probes, chips and related testing equipment will be used in the field of rapid detection of drinking water and food.Nano-ceramic probes have high accuracy and convenience, can be detected at the terminal in real time, can be immediately transmitted and feedback, and can effectively improve the efficiency of big data evaluation of food hygiene.Tianyancha’s public information shows that the registered capital of the “Three Rings Raman Chip” is RMB 53.04 million, and Chen Cheng, Chairman and President of the Three Rings Group, is the legal representative.In addition, Guangxi Sanhuan Ceramic Town holds 75.4%, and Huakong Technology Transfer Co., Ltd. holds 7.38%.Among them, Guangxi Sanhuan Ceramic Town is 100% controlled by Guangxi Sanhuan Enterprise Group Co., Ltd., and Huakong Technology is 100% controlled by Tsinghua Technology.The financing round and specific funds have not been disclosed.Image source: Tianyancha According to public information, “Guangxi Sanhuan Enterprise Group” is an enterprise group that mainly produces daily-use ceramics, integrating science, industry and trade. It has a district-level technology center and a ceramic research institute in Guangxi.The company has more than 10 member companies, with a scale of more than 8,000 people, and produces 190 million pieces of daily porcelain.In 2019, Sanhuan Group successfully signed a nano-ceramic probe project at the 16th China-ASEAN Expo, and reached a strategic cooperation with Dr. Tsinghua’s team at the end of this year to register a new company, which means that Sanhuan Group plans to cut into high technologyCeramics and functional ceramics market.It is reported that the “three-ring Raman chip” mainly relies on Tsinghua University’s patented technology and the production capacity of the three-ring group to build the competitiveness of the industry. The core nano-ceramic probe project already has industrial production conditions.In terms of the core team, several shareholders holding shares are professors and academicians of the Tsinghua Department.Among them, Zhang Zhengjun holds 15% of the shares. He was the former Dean of the Institute of Materials Science and Engineering of Tsinghua University. He is currently a serving professor of Tsinghua University.Behavior; Ling Yunhan is a professor at the School of Materials, Tsinghua University. He has long been engaged in wet extraction of non-ferrous metals, nano-processing, development of new functional materials, and research on electrochemical application technology.
