In the name of God
Major (Course): Nanochemistry
Introduction: In the broadest sense, nanochemistry employs the tools of synthetic chemistry and materials chemistry to make nano-materials with size, shape, and surface properties that are designed to evoke a specific function and orchestrated to target a particular end use. These building blocks of nanochemistry may have value on their own, such as a nanocrystal single-electron transistor, or instead it may be groupings of these building blocks that are relevant, being self-assembled into structures or patterns that offer a clear function and utility, for example, a semiconductor nanowire electronic circuit. In the beginning, the excitement of nanochemistry was in the size- and shape-dependent properties of nanomaterials, which were perceived as a treasure trove of opportunities for the bottom-up chemical control of the behavior of materials. This approach represented a dramatic shift from the traditional top-down nanofabrication methodology based on carving out nanostructures from planarized bulk materials by using photon, electron, atom, and ion beams practiced in engineering and physics for many decades. In those early days, the great appeal of a synthetic approach to nanomaterials was the ability to create nanoscale building blocks of any composition: inorganic, organic, polymeric, biological, and hybrid versions thereof. Chemistry was uniquely placed to achieve nanometer-precise command of the size, shape, surface structure, charge, and functionality of these building blocks. Moreover, this set of skills was setting the stage for the control of their self-assembly in a massively parallel fashion to create designed architectures that exhibited hierarchical structure and function to enable a purposeful application .
