Nanomaterials describe, in principle, chemical substances or materials of which a single unit is sized (in at least one dimension) between 1 and 100 nm (the usual definition of nanoscale [1]). Nanomaterials research takes a materials science -based approach to nanotechnology , leveraging advances in materials metrology and synthesis which have ...
The conceptual foundation for DNA nanotechnology was first laid out by Nadrian Seeman in the early 1980s. [2] Seeman's original motivation was to create a three-dimensional DNA lattice for orienting other large molecules, which would simplify their crystallographic study by eliminating the difficult process of obtaining pure crystals.
Design, analysis, and construction of systems of molecular parts working together to carry out a useful purpose. Molecular Wire A molecular wire - the simplest electronic component - is a quasi-one-dimensional molecule that can transport charge carriers (electrons or holes) between its ends.

InGaN/GaN nanorod array light-emitting diodes can be manufactured with dry etching or focused ion beam etching techniques. [6] Such LEDs emit polarized blue or green light [7] Three-dimensional nanorod structures have a larger emitting surface, which results in better efficiency and light emission compared to planar LEDs. [8]
Nanochemistry is an emerging sub-discipline of the chemical and material sciences that deals with the development of new methods for creating nanoscale materials. [1] The term "nanochemistry" was first used by Ozin in 1992 as 'the uses of chemical synthesis to reproducibly afford nanomaterials from the atom "up", contrary to the nanoengineering and nanophysics approach that operates from the ...
Nanocomposite is a multiphase solid material where one of the phases has one, two or three dimensions of less than 100 nanometers (nm) or structures having nano-scale repeat distances between the different phases that make up the material.
Nanoparticles differ in their physical properties such as size, shape, and dispersion, which must be measured to fully describe them. The characterization of nanoparticles is a branch of nanometrology that deals with the characterization, or measurement, of the physical and chemical properties of nanoparticles.,. [1]
The science behind this mechanism is quite complex. Passage of cells across the blood endothelium , a process known as transmigration, is a mechanism involving engagement of cell surface receptors to adhesion molecules, active force exertion and dilation of the vessel walls and physical deformation of the migrating cells.
