Nanopore is a pore of nanometer size, which is formed by protein or as a hole in synthetic materials such as silicon or graphene. Nanopore technology is a unique, scalable technology that helps in making direct, realtime analysis of long DNA or RNA fragments. Furthermore, these technologies are used as a single-molecule detector.

Nanochemicals are produced using nanotechnology which exhibit enhanced properties such as self-catalysis and anti-corrosion. Increased demand for nano chemicals owing to maximum product yield has propelled the growth of nanochemicals in the industry. Moreover, the enhanced chemical reaction timing has also led to the adoption of nanochemicals, which in turn drives the nanochemicals market growth. In addition, these nanochemicals have wide applications in manufacturing, paints & coatings, automotive, pharmaceutical, and other industries that contributes toward higher demand for nanochemicals which notably boosts the nanochemicals market growth. However, hazardous nature of the chemicals owing to quick reactions can restraint the market growth.
