The Role Of Self Assembly And The Construction Of A Nanostructure

Good Essays

A nanoparticle is the most basic component in the construction of a nanostructure. In general, the size of a nanoparticle spans the range between 1 and 100 nm. The properties of many conventional materials change when formed from nanoparticles. This is typically because nanoparticles have a greater surface area per weight than larger particles which causes them to be more reactive than other molecules. Self-assembly refers to the process by which nanoparticles or other distinct components spontaneously organize due to direct specific interactions and/or indirectly, through their environment. Self-assembly is typically linked with thermodynamic equilibrium, the organization of the structures characterized the minimum of the system’s free energy. An important aspect of self-assembly is that the building blocks organize into macroscopic structures. This can happen through direct interactions (Interparticle forces) or through indirect interactions like using a template or external field as a guide. The grouping of matter in nanomaterials can be broken down into two techniques. Top-down miniaturization techniques or bottom-up methods which are typically based on self-assembly or directed assembly. The most widely used materials in bottom-up assembly are colloid micro- and nanoparticles. A lot of time and effort has recently been spent on the fabrication of functional materials from organized particles. These advanced assemblies can find applications in areas such as photonics,
