Now so many so-called nano-nano things are basically advertisements. At present, I can tell you that there are not many things that really need that kind of nanotechnology. There are only a few things that are really used at present.
Chips, especially processor chips, such as those in your computer, really use nanotechnology.
Look at the processors of Intel and AMD now. 65 nm process and 45 nm process are already nano-scale. They cut silicon wafers and make circuits by changing the positions of silicon atoms. So, this is nanotechnology.
Other light bulbs, refrigerators and televisions are all talking about nanotechnology. This is just an advertisement, which is meaningless at all, because there is no need for nanotechnology in those places.

Nanotechnology application report
The application of nano-material technology in automobile, the development of automobile technology depends on the development of material technology, and the application of nano-technology in automobile, which is now popular all over the world, has laid the foundation for the development of new material technology. Nanometer is the unit of measurement, and 1 nanometer is one millionth of a millimeter. Such a tiny space is actually the basic unit of matter and becomes the space of atoms and molecules. Since the invention of the electron scanning tunneling microscope in the early 1980s, a micro-world research discipline-nano-science has been born in the world. The technology of studying and treating micro-structured substances below 100 nm is called nanotechnology. In the 1990s, nanotechnology developed rapidly, resulting in nano-materials, nano-chemicals, nano-mechanics and nano-biology, and the resulting nano-technology products emerged one after another, and began to involve the automobile industry. What about automotive nanotechnology? Experts predict that nano-interface material technology, that is, super-amphiphilic binary synergistic interface material technology (hydrophilic and lipophilic) and super-double hydrophobic interface material technology (hydrophobic and oleophobic), can be realized on any material surface. Therefore, if these two technologies are applied to domestic rubber materials, the problems of oil leakage and oil seepage that plague domestic cars will be solved. More and more plastics will be used in automobile manufacturing. Nano-plastics can change the characteristics of traditional plastics and show excellent physical properties: high strength, strong heat resistance and smaller specific gravity. Because the size of nanoparticles is smaller than the wavelength of visible light, nano-plastics can show good transparency and high gloss, and such nano-plastics will be widely used in automobiles. The wear resistance of some materials treated by nanotechnology is 27 times that of brass and 7 times that of steel. For example, nano-ceramic bearings have been applied to luxury cars such as Mercedes-Benz. At present, China has developed an emulsifier made of nanotechnology. The fuel consumption of a car like Santana can be reduced by about 10% after adding a certain proportion of gasoline. More notably, the application of nanotechnology in fuel cells can save a lot of costs. Because nanomaterials have excellent hydrogen storage capacity at room temperature. According to the experimental results, these nano-materials can release about 2/3 of hydrogen energy at normal temperature and pressure, so they can replace the expensive ultra-low temperature liquid hydrogen storage device. The School of Chemistry and Molecular Science of Wuhan University has made a breakthrough in the research of nanometer titanium dioxide. Using the patented technology of Wuhan University to produce nanometer titanium dioxide, its cost is only about 1/4 of that of foreign countries. The appearance of nanometer titanium dioxide is a new progress in the research field of titanium dioxide at the end of 1980s. Scientists in Japan and the United States have found that this substance can be widely used in the metal topcoat of luxury cars. In Japan, photocatalytic plates coated with nano titanium dioxide are set on both sides of highways and tunnels to remove nitrogen oxides and prevent automobile exhaust. At present, only a few companies in the world can produce nanometer titanium dioxide. I believe that in the near future, nanotechnology will be more widely used in the field of automobile manufacturing. Application of nanotechnology in photoelectric field Nano electrostatic shielding material is another important application of nanotechnology, and it is also the application of nanotechnology in bioengineering.

How is nanotechnology caused?
Based on nanotechnology, nanotechnology studies the properties and applications of materials with structural dimensions in the range of 0. 1 ~ 100nm, as well as the methods and means to manufacture new materials, devices and research new processes. Nanotechnology is based on the microscopic research theory of physics and chemistry, and it is the product of the combination of modern science (chaotic physics, quantum mechanics, mesoscopic physics and molecular biology) and modern technology (computer technology, microelectronics, scanning tunneling microscope technology and nuclear analysis technology) with the help of modern precision instruments and advanced analysis technology. From 65438 to 0993, the International Steering Committee of Nanotechnology divided nanotechnology into six sub-disciplines: nanoelectronics, nanophysics, nanochemistry, nanobiology, nanofabrication and nanometrology. Among them, nano-physics and nano-chemistry are the theoretical basis of nano-technology, and nano-electronics is the most important content of nano-technology. Nanotechnology is a new technology developed rapidly in the early 1990s. Its ultimate goal is that human beings can directly manipulate individual atoms and molecules according to their own consciousness to produce products with specific functions. Nanotechnology reveals the visible world of atoms and molecules with unprecedented resolution. This shows that people's understanding of the micro-world is getting deeper and deeper, and people's understanding and transformation level of the micro-world has improved to an unprecedented height. According to some data, in 20 10, nanotechnology will become the second largest industry after chip manufacturing.

Application examples of nanotechnology in life
The application of nanotechnology in life actually covers all physical and chemical technologies and processes in the nanometer range, and it is not an exaggeration to say that it is all-encompassing. The equipment made of nano-materials has lighter weight, stronger hardness, longer service life, lower maintenance cost and more convenient design. Nano-materials can also be used to make materials with specific properties or materials that do not exist in nature, and to make biological materials and bionic materials. But now there are many hype concepts, many of which are confined to the theoretical stage of the laboratory. What is more realistic is the lubricant in machinery, the catalyst in chemical industry and the fixed-point super-effective medicine in medicine. The application of nanotechnology in the field of architecture can make a big difference. Indeed, some nanotechnology has been applied in the market. For example, in environmental protection projects, we have seen new smart materials mixed with nano-titanium dioxide particles and applied to the self-cleaning of windows, buildings and roads. In Milan, 7,000 square meters of roads have used these energy materials, thus reducing the level of nitrogen dioxide by 60%. Some nano-materials are also added to the new building materials, thus improving the mechanical strength, durability and insulation, and reducing the weight compared with traditional materials. For example, nano-ceramics are used in cement to increase strength. Sensor systems will be increasingly used in buildings, including monitoring the environment of buildings and the strength of any machinery. Sensor system Some sensor systems are used in buildings, similar to those discussed in the section on environment, but these sensors are mostly used to test the structural strength and wear of buildings, so as to let people know the potential safety hazards in buildings. When the sensor is connected to the heating/air-conditioning system, choose the best setting, and the data collected by the sensor can provide environmental monitoring and even temperature control for the building. Nanotechnology also helps to provide a detailed system-wide view of "architectural feeling". All sensors and monitoring data are transmitted to the central node for processing and then put into practice. Electronic participation will be less, but it will be equally (or even more) powerful. They will use energy more efficiently and even use small solar cells effectively for their own power generation. Therefore, it is possible to make the system maintenance-free and durable. Nano-household appliances At present, many electrical appliance companies have successively introduced novel nano-household appliances. The so-called nano-household appliances are household appliances produced by nanotechnology. In the nano-world, matter has made a qualitative leap. For example, copper with good conductivity does not conduct electricity at the nanometer level, while insulating silicon dioxide begins to conduct electricity at the nanometer level; Silicon dioxide ceramics are brittle under normal conditions, but when the particles of silicon dioxide ceramics are reduced to nanometer level, brittle ceramics have toughness. When substances are refined to nanometer level, artificial nanomaterials have special properties and great uses. Adding nano-materials to the plane can absorb radar waves, so the stealth plane comes out. Tools made of nano-materials are harder than diamond tools. Computer chips and optical disks are processed into nanometer scale, and the operation speed and recording density are higher than normal orders of magnitude. At present, nanotechnology is mainly used in the field of "healthy" household appliances such as antibacterial and bacteriostatic. For example, the nano-freezer currently on the market uses nano-treated materials in the parts where people's hands are easy to touch and bacteria are easy to invade, which can effectively inhibit the growth of bacteria, thus improving the antibacterial ability of the freezer. Nano-washing machine, that is, the outer barrel of the washing machine is made of nano-materials, which makes the washing machine not only resistant to high temperature and wear, but also resistant to scaling. It can be predicted that with more home appliance enterprises adopting nanotechnology, nano home appliances will become a hot product in the future market. At the same time, researcher Zhang Lide, the chief expert of the expert group on nanomaterials for major basic research in China, clearly pointed out: "Nanotechnology will have a wide and profound impact like information technology, which will be twenty or thirty years later."
