Nanochemistry

 

The study of the synthesis and characterization of materials in the nanoscale size range (1 to 10 nanometers). These materials include large organic molecules, inorganic cluster compounds, and metallic or semiconductor particles. The synthesis of nanoscale inorganic materials is important because the small size endows these particles with unusual structural and optical properties that may find application in catalysis and electrooptical devices. Approaches to the synthesis of these materials have focused on constraining the reaction environment through the use of surface-bound organic additives, porous glasses, zeolites, clays, or polymers. The use of synthetic approaches that are inspired by the biological processes result in the deposition of inorganic materials such as bones, shells, and teeth (biomineralization). This biomimetic approach involves the use of assemblies of biological molecules that provide nanoscale reaction environments in which inorganic materials can be prepared in an organized and controlled manner. Examples of biological assemblies include phospholipid vesicles and the polypeptide micelle of the iron storage protein, ferritin. See also Micelle.

Nanochemistry is the science of tools, technologies, and methodologies for chemical synthesis, analysis, and biochemical diagnostics, performed in nanolitre to femtolitre domains. Nanochemistry is the use of synthetic chemistry to make nanoscale building blocks of desired shape, size, composition and surface structure, charge and functionality with an optional target to control self-assembly of these building blocks at various scale-lengths.

The nanoscale spatial arrangement of chemicals such as ligands on a surface. For example, the same number of ligands (same bulk density) can be arranged into (separate/more distant) groups of two or more nearby ligands to more effectively match complex receptors structure and arrangement on cells (see Fig. 3).
