Naoparticles Lab Report - 803 Words

Nanoparticles show different and distinctive properties from the bulk materials and they can be incorporated in different fields such as, biomedicine, catalysis, and energy conversion, so they have gained significant considerations from the researchers in the last two decades. For example, biologist and scientists have just started to apply nano-pattering techniques to create detection systems for genomic studies. On the other hand, engineers and physicists are aiming to shrink the size of transistors and MEMS components by using the method of nanofabrication in order to make high performance electronic devices. In general, material properties are completely dependent on the structure, so changing the macroscopic bulk properties, such as†¦show more content†¦In addition, uniform inorganic nanoparticles of gold has been used extensively as drug carriers.^3 This proposal mainly seeks to discover two methods, which use salt powder as separation medium, for forming uniform inor ganic nanoparticles without the use of solvent. Innovations: The methods of hot injection and solution-based are usually used to create different types of uniform nanoparticles, such as Pd and Pt, by choosing the appropriate ligands or capping agents that lead to carefully control the size and shape of the resulting nanoparticles.^7 However, there are some disadvantages associated with using the previous methods to synthesize uniform nanoparticles because they require long time to get the resulting nanoparticles and large quantities of expensive solvent. In addition, 3D transition for metals is very difficult to be accomplished by using the previous methods. Additional annealing step also is required to get the desired crystallinity for the resulting nanoparticles, which might lead to the evaporation of the expensive solvent. Because of those disadvantages for above-mentioned methods that rely on the use of expensive or toxic solvent, solventless methods have obtained significant interest due to the fact that they are fast and they do not requ ire the use of expensive solvents. The innovation of this research will focus on the use of solventless methods to synthesize uniform inorganic nanoparticles.
