Grafting of the Organic Functional Groups to the Iron Nanoparticles Surface via Arenediazonium Tosylates

Abstract:

The nanoscale materials and their application have received considerable attention for the last few years owing to its potential use in biomedical fields of science and technology. Recent studies have demonstrated the ability of arenediazoniumtosylates (ADTs) to modify nanoscale materials. An efficient method of modifying zero-valent iron nanoparticles using ADT with different functional organic groups in a water suspension at the room temperature has been developed. Particle composition, size, stability and possible functionalization with ADT have been characterised by using the FT-IR and X-ray diffraction methods, the low-temperature nitrogen adsorption analysis (BET), TGA/DSC/DTA analyses in the air and the elemental analysis. The obtained methods and results are to foster better understanding of nanoparticles modification process and contribute to its further research and development due to the ability of changing functional groups in the ADT molecule for medical and other applications. Variation of the functional groups in the ADT molecule can change the properties of Fe-NPs and predetermine the field of their use.
