Compounds Nanoparticles

Compounds Nanoparticles List

Compounds nanoparticle is a nanoparticle with a specific organizational structure composed of two or more elemental components. Covalent bonds between different elements make the compounds nanoparticles have specific properties and composition, and make the entire system more stable. Compounds nanoparticles have unique mechanical properties, contact reaction activity, optical properties, electrical conductivity and other characteristics due to their nanometer particle size, and have gradually been widely used in the fields of optoelectronics, biomedicine, cosmetics, energy and catalysis.

Figure 1. Applications of compounds nanoparticles.

Applications:

• Pollutant treatment: The application of compounds nanoparticles in pollution remediation research has also received more and more attention. Nanoparticles can enhance a variety of interface reactions, such as surface adsorption of heavy metal ions and organic pollutants, specific adsorption and enhanced oxidation, reduction reaction, etc. The application of compounds nanoparticles is mainly concentrated in the field of organic/inorganic polluted wastewater treatment and the catalytic purification of polluted gases.
• Optical materials: One of the most important signs of nanoparticles is the size effect. When the size of the nanoparticle is related to the superconducting wavelength, Bohr radius and De Broglie wavelength of electrons, the quantum size effect of small particles is very significant. At the same time, the large specific surface area makes the behavior of the atoms and electrons in the surface state very different from the atoms and electrons inside the particles, so this surface effect and quantum size effect have a great impact on the optical properties of nanoparticles. Influence, even make the compound nanoparticles have new optical properties that the same material legal person macroscopic bulk object does not possess. The photoluminescence phenomenon of quantum dots is the most direct manifestation of the quantum size effect. Thus, compounds nanoparticles can be used as optical materials such as photonic crystals, nano lasers, solar cells, and cell imaging.
• Biomaterials: Nanoparticles are widely used in the immobilization of proteins or enzymes, targeted drug delivery, cell separation, and medical imaging due to their large specific surface area, relatively high saturation magnetic moment, and easy functionalization of the surface. Nano-silica, as a compound nanoparticle material, has a special structure level. SiO2 nanoparticles have good water solubility, so that they can be easily dispersed in the solution. SiO2 nanoparticles are not cytotoxic, and their good biocompatibility makes them not cleared by macrophages in the living body, so they can be used in organisms.
• Magnetic materials: Metal compounds nanoparticles have good magnetic guidance, biocompatibility and biodegradability, etc., and can bind a variety of biological functional molecules. Magnetic compounds nanoparticles are widely used in DNA separation and purification, magnetic targeted drugs, medical detection and diagnosis, gene therapy, adsorption and immobilization of proteases, etc.
