Regenerative medicine: develop nano-structured materials to guide tissue regeneration and promote tissue/material interface fusion, permanent implant surface coatings for tissue repair and replacement, scaffolds to guide tissue regeneration, structural permanent implants, sensors for implantable treatment and monitoring, etc.
Surgical assistance: develop intelligent instruments and equipment, surgical robots and diagnostic tools based on nano-optics and nano-electronics. Based on nanofluid and nano-processing technology, we will develop gene detection, ultra-sensitive labeling and detection technology, Qualcomm quantitative and multiple analysis technology.
Medical imaging: new contrast agents based on nanoparticle technology, targeted labeling technology, and understanding of basic life processes: based on nano-mechanical and optical technologies such as atomic force microscope and tunneling scanning microscope, life processes are studied at the molecular or atomic level.
Extended data
Imaging technology can only detect the visible changes caused by cancer in tissues, while thousands of cancer cells have been produced and may metastasize.
Even though the tumor can already be seen, due to the category (malignant or benign) and characteristics of the tumor itself, it is necessary to determine the effective treatment method through biopsy. If cancer cells or precancerous cells are labeled in some way, they can be detected by traditional equipment, which is more conducive to the diagnosis of cancer.
To achieve this goal, there are two necessary conditions: a technology can specifically identify cancer cells and make the identified cancer cells visible. Nanotechnology can satisfy these two points. For example, the surface of metal oxide is coated with antibody, which can specifically recognize the receptor over-expressed on the surface of cancer cells.
Because metal oxides will emit high-contrast signals under magnetic resonance imaging (MRI) or computed tomography (CT), once they enter the body, the antibodies on the surface of these metal oxide nanoparticles will selectively bind with cancer cells, so that the detection instrument can effectively identify cancer cells.
Similarly, gold nanoparticles can also be used to enhance light scattering in endoscopic technology. Nanotechnology can visualize molecular markers that identify cancer types and different stages of development, so that doctors can see cells and molecules that cannot be detected by traditional imaging techniques.

Can nanotechnology make people understand more healthily?
What are the nanotechnology with rewards? What, where can nanotechnology be used in life? Let me answer the question: There is a reward Zy3760339 LV.8 2020-03-22 Talk about the application of nanotechnology in life, which is reflected in food, clothing, housing and transportation. 1. Adding nanoparticles to textiles and chemical fiber products can deodorize and sterilize. Although chemical fiber cloth is strong, it has annoying static phenomenon, which can be eliminated by adding a small amount of metal nanoparticles. 2, the use of nano-materials, refrigerators can be antibacterial. Sterile tableware and aseptic food packaging products made of nano-materials have come out. By using nano-powder, wastewater can be completely turned into clean water, which fully meets the drinking standards. Nano food is delicious and healthy. 3. With the application of nanotechnology, the washability of wall coatings can be improved by 10 times. Self-cleaning glass and self-cleaning tiles can be made by coating nano-thin layers on the surfaces of glass and tiles without scrubbing at all. Building materials containing nanoparticles can also absorb ultraviolet rays harmful to human body. 4. Nano-materials can improve the performance of vehicles. Nano-ceramics are expected to become ideal materials for engine parts such as automobiles, ships and airplanes, which can greatly improve the efficiency, working life and reliability of engines. Nanosatellites can provide drivers with traffic information at any time to help them drive safely. Nano-materials are new materials developed in the mid-1980s, which are 50 years ahead of negative oxygen ions. Due to the unique structural state of nanoparticles (1- 100nm), small size effect, quantum size effect, surface effect, macroscopic quantum tunneling effect, etc. This makes nano-materials show special functions, such as light, electricity, heat, magnetism, absorption, reflection, adsorption, catalysis and biological activity. Nano-materials have many unique functions, but the dosage is very small, but they give materials unexpected high performance and high added value. Nano composite polymer materials, nano antibacterial, fresh-keeping and deodorizing materials, etc. Because of their small size, they are more than 1000 times smaller than red blood cells in blood and dozens of times smaller than bacteria, and the diffusion speed of gas through them is thousands of times faster than that of conventional materials. Nanoparticles have a strong interaction with biological cell membrane compounds and can easily enter cells.
