Cobalt nanoparticle [1]

Nanochemistry or Nanotechnology are related with the production and the reactions of nanoparticles, nanostructures and their compounds. It is concerned with the unique properties associated with assemblies of atoms or molecules on a scale between that of the individual building blocks and the bulk material (from 1 to 1000 nm[2]). At this level, quantum effects can be significant, and also new ways of carrying out chemical reactions become possible.

This science use methodologies from the synthetic chemistry and the material's chemistry to obtain nanomaterials with specific sizes, shapes, surface properties, defects, self-assembly properties, designed to accomplish specific functions and uses.[3] Nanomaterials can be created from virtually any material, such as metals, semiconductors and polymers, both in their amorphous and crystaline forms.

Nanochemical methods can be used to create carbon nanomaterials such as carbon nanotubes (CNT), graphene and fullerenes which have gained attention in recent years due to their remarkable mechanical and electrical properties.

Applications[edit]

There are a wide range applications of nanochemistry fabrication, such as semi-conductors electronics, advanced composite materials (e.g. carbon nanotube polymers), colloidal particles (e.g. in paint products), medicine etc. Nanochemistry uses semi-conductors that only conduct electricity in specific conditions.

There is evidence certain nanoparticles of silver are useful to inhibit some viruses and bacteria.[4]

Examples[edit]

Nanochemistry is being used to build high-tech armor and weapons and for military uses. Nanochemistry could also be used for Chemical Warfare.

Nanochemistry is also used to make windows that clean themselves, along with bicycles that are 1000 times stronger than steel but lighter than metal ones. The most productive piece of Nanochemistry is Carbon Nanotubes which are very dense and light when made into materials such as bicycles. Nanochemistry could be very useful in the future.
