An Introduction to Nanoscience and Nanotechnology

From atoms to molecular self-assembly, we are witnessing the continual emergence of new properties.
The most complex edifices, ie molecules, are organized by the grouping together of atoms. It is the properties of these molecules that give us the world in which we evolve.
In fact, the grouping of atoms reveals the notion of functionality; from acid carrying hydrogen with one atom, up to large molecules in living organisms, genes and long chains of molecules assembled in a helix. The latter carries the building blocks of living organisms [2] which are not only present in the nanoworld but also in our world.
The extraordinary subtlety of the hydrogen bond means that humanity is unable to work out the different characteristics of its phases; for example, a liquid which solidifies itself into an ice crystal is less dense than water. Water is necessary for life on earth. Another example is a solid snow structure whose infinite complexity allows researchers to carry out up-to-date research in order to optimize the friction coefficient. We are witnessing the emergence of new properties which are replacing those of their atomic components. This will be the same for structures with an increasing complexity.
These molecules, which have enormous edifices with multiple configurations and functions, have developed a soft chemical catalyst by using the lock and key effect to interact. Here, an atom...
