Recently, Russian scientists used laser technology to create a new optical biosensor. Compared with traditional sensors, its sensitivity has been greatly enhanced, can be used to detect bacteria and viruses, especially suitable for use in high-traffic scenarios, such as the airport. Thanks to the grating-like structure of a silver film, infrared light is regularly distributed over its surface as it passes through the sensor. As the light intensity becomes higher, the microwell will turn into a hot spot. The microorganisms contained in the biological material effectively fill the pores and adsorb the hot spots, thereby increasing the probability of detection. The researchers said: "With this technology, optical biosensors can be used to detect individual bacteria, which can be very helpful in disease prevention and rapid diagnosis."
The barbed wire is twisted and braided by a fully automated barbed wire machine. Commonly known as tribulus terrestris, barbed wire, and barbed thread among the people. Finished product types: single-filament twisted and double-filament twisted.

Raw materials: high-quality low-carbon steel wire.
Surface treatment process: electro-galvanized, hot-dip galvanized, plastic-coated, spray-coated. There are blue, green, yellow and other colors.
The reason for surface treatment is to enhance the anti-corrosion strength and prolong the service life. As the name suggests, the surface treatment of galvanized barbed wire is galvanized, which can be electro-galvanized or hot-dip galvanized; the surface treatment of PVC barbed wire is PVC-coated, and the barbed wire inside is black wire, electroplated wire and hot-dip galvanized wire.
Uses: Used for the isolation and protection of grassland borders, railways, and highways.
