Release date: 2007-01-23 Shanghai developed a successful nano-detector for the diagnosis of hepatitis According to reports, Shanghai Jiaotong University Science and Technology Research Institute recently developed a "nano-detector" multi-functional biomedical tool - nano magnetic microspheres. It can be used for rapid detection of biomedical fields such as hepatitis, AIDS, and myocardial infarction. It can also participate in food safety testing such as Sudan red and pesticide residues.
Green Peas, According to the color of their cotyledons, Peas are divided into two types: green skin, green peas, and
green skin yellow peas. Green peas are green-green peas. Peas in northeast China are the most famous. It is one of China's
important food crops. It has a history of 5,000 years of cultivation. Our company can provide two different frozen peas to meet the needs of different people.

The scientific name of "nano-detector" is "monodisperse high-magnetic responsive nano-magnetic microspheres". The total amount of magnetic particles contained in each microsphere exceeds 70%. Under the action of a magnetic field, a large number of nano-magnetic microspheres can be accurately " Grab the "detection object" and "centralize transportation" to the designated location and quickly detect it.
At present, Shanghai Jiaotong University replaces the optical signals commonly used in disease detection with the magnetic signals of magnetic microspheres, which improves the detection sensitivity of major infectious diseases such as HIV, hepatitis B virus and hepatitis C virus by 10 to 100 times. At the same time, the entire detection time is shortened to only about 20 minutes to obtain quantitative results. Shanghai Medical Devices
The effect and effect of green peas
Daily
green peas can provide catechins and epicatechins as two kinds of
flavonoid antioxidants. When people get older, there will be more and
more free radicals in the body. Free radicals and aging are positively
related. Nutrition in green beans can resist. Free radical-induced diseases, delaying the speed of body aging, as well as anti-inflammatory, spectral antibacterial effects.
