Nano chemicals are materials that are manufactured at a scale that is 10 thousand times smaller than the size of human hair. Nano chemicals are developed to bring forth increased characteristics, compared to the same chemical without nano scale attributes.

Nano chemicals are already in use and they can be seen in many sectors including industry, health, innovation. More than 1300 commercial products are manufactured from nanomaterials. Nanomaterials are very effective, but there is poor information about how nanomaterials endanger ecosystem health. Nanomaterials have smaller than normal sizes, thus they are absorbed more easily by animal's skin and lungs. Nanomaterials interfere with biological processes, which are significant to the health of ecosystems.

Researches about nanomaterials are evaluating the life cycle of commercial nanoproducts, starting with raw material extraction and ending with the ultimate disposal. Innovative technologies are developed and used to produce nanomaterials. These technologies have no impacts on health and environment.

Nano chemicals are chemical substances or materials that are manufactured and used at a very small scale (down to 10,000 times smaller than the diameter of a human hair). Nano materials are developed to exhibit novel characteristics (such as increased strength, chemical reactivity or conductivity) compared to the same material without nanoscale features.
