Marshall and his collaborator Warren discovered Helicobacter pylori, which is the pathogen that causes the most common and important disease of human gastric ulcer, and won the Nobel Prize for it. It is closely related to all kinds of living environment pollution in the city. Green, low-carbon and new energy technologies can improve the urban environment, thus ensuring the health of urban residents.
nanotechnology
Nanotechnology is a science and technology to manufacture substances, operate and process nano-scale (generally less than 100 nm) materials or devices based on atomic and molecular levels. Its main research content is the properties and applications of materials with structural sizes from 1 to 100 nm.
Nanotechnology is a kind of high-tech that can manipulate objects as small as nanometer scale. Due to the existence of quantum effect and size effect, materials constructed on nano-scale often show obviously different physical and chemical properties from macroscopic materials. Both biochip and biosensor can belong to the category of nanotechnology.
Nanoscience and technology are the product of the combination of dynamic science, modern science and modern technology, and many new branches of disciplines have been derived, such as nanophysics, nanobiology, nanochemistry, nanoelectronics, nanoprocessing technology and nanometrology, which will trigger a new technological revolution.
