Specific nanoparticles are designed in order to deliver the different materials. Controlling the size, shape of nanomaterials during nanoparticles synthesis leads to effective synthesis of nanoparticles that can be combatable to electrical system. Iron based nanoparticles are most efficient due to low cost and high adsorbent efficiency as compared to the other nanoparticles through the action of magnetic field with ionic exchange capacity for heavy metals removal. Nanofilters are used for filtering the chemical pollutants found in wastewater. Acid treatment leads to precise synthesis of nanoparticles through the formation of biopolymers that can be disintegrated into smaller components or individual’s molecules. Gold nanoparticles are also much reliable as compared to the other nanoparticles as they are more influenced by the intensity of light. Scanning tunneling microscopy has become technique to provide the electric data about the specific atom or particles by following the princes of scanning under chemical investigation. X-ray spectroscopy is used for the analysis of that analysis usually heavier than oxygen. Electron energy loss spectroscopy (EELS) that detect the particular nanoparticles by loos of energy by passing through the samples or specimen.
