Note: Active Nano particles  are  of great interest in both industry and natural sciences due to their wide application.  While natural materials have constant physical properties regardless of size, the size of a nanoparticle determines its physical and chemical properties.

 Therefore, the properties of a material change as its size approaches the nanoscale and the percentage of atoms on the surface of the material becomes significant. The important feature of all nanostructures is that the number of surface atoms in them is more than the number of volume atoms. This ratio increases with decreasing nanoparticle size. Therefore, the size of the nanoparticle is considered its most important feature. The range of activity of nanoparticles depends on the nature and shape of the nanostructure. However  , if the energy of the nanoparticle field is comparable to the energy of electromagnetic radiation and if  significant changes are made in a certain wavelength range with the occurrence of chemical reactions in the irradiated materials, the activity of nanoparticles  up to 100nm will be significant.



The use of particles from the microscale to the nanoscale provides advantages for various scientific fields, but because a large percentage of their atoms are on the surface, nanomaterials can be highly reactive and pose potential hazards to humans. to bring The surface atoms of nanoparticles are not compensated in terms of energy. In general, the results of  nanoparticle energy growth can be expressed as the total energy of atoms on the surface of the particle. The freedom of movement of atoms on the surface of nanostructures  is limited and only vibrational movements and the movement of electrons are possible. These two electrokinetic reactions  are dependent on each other because the displacement of electron clouds of atoms definitely changes the vibrational frequencies of the bonds of atoms of nanoparticles  . On the other hand, changing the location of valence electrons in the bonds changes the polarity of the bond and the bodies known as supermolecules  . In this case, electron transfer to a higher energy level becomes possible. In this sense, carbon nanotubes (CNTs) are the most interesting investigated species. In this, the  carbon nanotubes that protect them from the environment interact, and for this reason, these CNTs nanotubes are  called metal/carbon nanotubes.


Conclusion: 

The use of particles from the microscale to the nanoscale provides advantages for various scientific fields, but because a large percentage of their atoms are on the surface, nanomaterials can be highly reactive and pose potential hazards to humans. to bring along
