| Description |
Nanoparticles are structures with dimensions on the order of tens of nanometers. Their synthesis, characterization and utility have been extensively studied over the last two decades. The importance of these materials arise from the fact that they provide unique surfaces (due to large surface to volume ratio) on which novel chemical reactions can be initiated. Moreover both their physical and chemical properties are known to be altered. As a result, finding new facile ways of synthesis of nanoparticles (NPs), especially if the preparations require minimal stringent conditions and are adaptable to a wide variety of chemical compositions are always sought after. This paved the way for the usage of amino acid based ionic liquids (AAILs) in the synthesis of metal NPs. It should be noted that these AAILs act as a self-reducing and capping agents for the formation of a wide variety of MNPs. Also, a new amino acid derived amphiphile, lauryl ester of tyrosine (LET) was found to provide a facile methodology for the preparation of hollow silica spheres. A detail procedure would be presented, where air droplets are capped with LET aggregated structures and in turn utilized as viable templates for the production of hollow silica spheres.
