Nanotechnology is the science and technology of making substances with single atoms and molecules. It studies the properties and applications of materials with structure sizes ranging from 1 to 100 nanometers. In the process of analyzing the composition of substances, scientists have found that several or dozens of countable atoms or molecules isolated at the nanometer scale have shown many new characteristics, and the technology that uses these characteristics to make devices with specific functions Is called nanotechnology. Now I am going to introduce three incredible applications of nanotechnology.
A new type of nanoparticle helps people lose weight efficiently
Researchers at Massachusetts Institute of Technology and Brigham and Women's Hospital have teamed up to develop a nanoparticle that can be used to lose weight. This kind of nanoparticle can directly deliver weight-loss pills to adipose tissue. After being treated with the nanoparticles, obese rats lost 10% of their body weight in 25 days without any side effects.

The weight-loss drugs used by researchers work by transforming white adipose tissue into brown adipose tissue. This pill is not new. The research team just invented a new type of nanoparticle to transport medicines and accumulate them in adipose tissue, avoiding side effects on other tissues in the body.
According to statistics, more than a third of Americans are considered obese. Last year, 20% of the 600,000 cancer deaths in the United States were caused by obesity. So many people need to lose weight. If you think of weight loss as just dieting and exercise, then it's a bit too simple. According to a recent survey, successful cases of losing weight through exercise have led many people to become obese again after years of stopping exercise. And that's why many scientists have sought to help us fight the obesity gene for years.

This method of losing weight uses nanoparticles to deliver drugs to specific adipose tissue, transform damaged fat cells, and achieve the effect of burning fat. It is more effective and fast, making weight loss a simple thing.
Nanoparticles: make germs "nowhere to hide"
Escherichia coli and Staphylococcus aureus are ubiquitous, and infections caused by these two bacteria have become a worldwide health problem. Escherichia coli can easily cause a series of food poisoning symptoms such as diarrhea, vomiting, and fever.

Recently, Dong Wenfei's team at the Suzhou Medical Institute of the Chinese Academy of Sciences has improved a magnetic mesoporous nanoparticle, which can be applied to bacteriostatic materials to make Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus disappear. The surface of the nanoparticle is positively charged, and the surface of the bacteria is negatively charged. Through electrostatic action, the purpose of capturing and separating Escherichia coli and Staphylococcus aureus can be achieved.

Magnetic nano-platforms have outstanding properties of capturing, separating and removing bacteria. These multi-functional platforms may greatly promote the development of clinical diagnosis, environmental testing and food safety.
Applications of nanoparticles in environmental governance
With the rapid development of industry, a large number of pollutants are discharged into the environment, which has caused many environmental problems, such as soil, water, and air pollution. And they have posed a threat to the ecological environment and human health.

In recent years, with the rise and development of nanotechnology, various nanomaterials have been widely used in the disposal of environmental pollutants. Compared with traditional materials, nanomaterials have the advantages of large specific surface area and many active sites, and are considered to be excellent materials for handling many pollutants.

At present, there are many types of environmental nanomaterials involved, which are mainly divided into natural nanomaterials and synthetic nanomaterials. There are a large number of minerals with nanostructures in nature, such as clay minerals and iron and manganese oxide nanoparticles. Among them, clay minerals are the most widely used in environmental governance. Compared with natural nanomaterials, synthetic nanomaterials are more pure in composition, more diverse in structure, and more prominent in performance.
