What are properties of nanoparticles?

What are properties of nanoparticles?The main parameters of interest with respect to nanoparticle safety are:

  • Physical properties:
  1. Size, shape, specific surface area, aspect ratio
  2. Agglomeration/aggregation state
  3. Size distribution
  4. Surface morphology/topography
  5. Structure, including crystallinity and defect structure
  6. Solubility
  • Chemical properties:
  1. Structural formula/molecular structure
  2. Composition of nanomaterial (including degree of purity, known impurities or additives)
  3. Phase identity
  4. Surface chemistry (composition, charge, tension, reactive sites, physical structure, photocatalytic properties, zeta potential)
  5. Hydrophilicity/lipophilicity

One of the important areas of nanotechnology is the production of nanoparticles. Basically, particles at the nanometer scale have two important properties:

  • Classical physics laws are no longer effective; and laws and principles of quantum mechanics are used to analyze their properties.
  • By decreasing the size of such particles, the surface-to-volume ratio of the system increases, which increases the effective surface area and thereby improves the efficiency of the physical and chemical processes at the surface, especially the catalytic reactions and increases their solubility.

These new properties make nanoparticle performance and applications possible in advanced fields of technology and industry.

What are the most important uses of gold nanoparticles?

What are the most important uses of gold nanoparticles?
Gold nanoparticles can act as catalysts and convert carbon monoxide to carbon dioxide. Composite materials with one- or two-dimensional arrangement of gold nanoparticles are attractive for making nanoscale instruments. Gold nanoparticles are also detectable. At present, living cells are studied using Raman spectroscopy. In Raman spectroscopy, laser light is applied to some materials with wavelengths often reversed by the wavelengths of the light molecules of the material. The introduction of gold nanoparticles into the cells amplifies the Raman signals by 5x, as the surface electrons of the nanoparticles interfere with the light scattering from the cell and amplify it.

Gold nanoparticles as nanocatalysts in the removal of pollutants by cleaning the exhaust gases of cars increase the intensity of favorable chemical reactions. Gold particles become smaller, softer, and more flexible at the nanoscale, so materials that react with these nanoparticles will be allowed to move and interact, making gold very active at the nanoscale. Gold nanoparticles can even kill cancer cells. These particles can attach themselves to cancer cells through a biocompatible molecular coating. The laser can heat these particles and continue to kill the cancer cells, and they can also act as a detector when viewing biological molecules with an electron microscope. Gold nanoparticles can also be used as components of electrical circuits in nanoelectronics.
