Nano selenium is mainly used in the fields of biomedicine and food processing, and biosynthesis is the mainstream preparation method
Nano selenium refers to the element selenium prepared by nanotechnology, and its size is at the nanometer level. Nano selenium has the advantages of low toxicity, large specific surface area, good chemical stability, good biocompatibility, good absorption, and high bioavailability, and is mainly used in biomedicine, agriculture, food processing, environmental protection, textiles, electronic devices and other fields.
The preparation methods of nano selenium include biosynthesis, physical synthesis and chemical reduction. The biosynthesis method has the advantages of green environmental protection, good quality of finished products, high yield of finished products, etc., and is the mainstream preparation method of nano selenium, which can be subdivided into two types: microbial fermentation method and efficient synthesis method of specific strains. Microbial fermentation method refers to the preparation of finished products by fermentation, separation, purification and other processes using microorganisms such as Staphylococcus koszii, silver-resistant soil bacillus and Larneella aquatic as substrates.
Nano selenium is widely used in many fields, including biomedicine, agriculture, food processing, environmental protection, textiles, electronic devices, etc. In the field of agriculture, nano selenium can increase the selenium content and nutritional value of grains, and can be used as fertilizer additives; In the field of environmental protection, it is absorbable and can remove heavy metal ions in water, and is widely used in water treatment scenarios. In the textile field, adding it to textiles can improve the stain resistance and antibacterial properties of textiles.
According to the "2024-2029 Research Report on the Application Market Demand and Development Opportunities of China's Nano Selenium Industry" released by the Xinsijie Industry Research Center, the biomedical and food processing fields are the largest demand for Nano Selenium. In the field of biomedicine, nano-selenium has the effects of improving immunity, antiviral, antioxidant and anti-tumor, and can be used to manufacture drugs for the treatment of cardiovascular diseases and cancer. In the field of food processing, it has the effect of preserving freshness and improving the nutritional value of food, and can be used as a food additive. At present, limited by factors such as high production costs, the production capacity of nano selenium in mainland China is low, and the market share is relatively small. In the future, with the improvement of technology maturity, the production cost of nano selenium in mainland China is expected to be reduced, and the development speed of its industry will be further accelerated.
At present, the concentration of nano selenium industry in mainland China is low, and the market is dominated by small and medium-sized enterprises. Hangzhou Selenium Yi Biotechnology Co., Ltd., Zhejiang Weifeng Biotechnology Co., Ltd., Shanghai Sitong Nano Technology Port Co., Ltd., Guangdong Jichuang Selenium Source Nano Research Institute Co., Ltd. are the main manufacturers of nano selenium in mainland China.
Industry analysts said that nano selenium, as a nano material, is widely used in many fields, and the development prospects of the industry are good. In terms of technology, the biosynthesis method has the advantages of green environmental protection and high yield of finished products, and is the mainstream preparation method of nano selenium. In terms of market competition, there are many nano selenium production enterprises in mainland China, and there is a lack of leading enterprises in the industry. It is expected that in the future, enterprises with high-quality nano selenium mass production capacity will occupy more space in the mainland market.
