What's with nanotechnology?

"Na" is the unit of length of matter, equal to one billionth of a meter.

When the substance is small to nanometer scale, it may show characteristics beyond or even different from large-scale substances in electronics, optics and mechanics.

As a drug carrier, nanoparticles have the advantages of high targeting, controlled drug release, improved drug dissolution and absorption rate. Some nanomaterials have also been proved to be efficient new drugs.

Nanomaterials are widely used in pharmaceutical industry because of their peculiar properties. For example, according to the fluorescence effect of quantum dots, the magnetic effect of magnetic nanomaterials, the adsorption effect of nanomaterials and so on. The sensitivity of detection can be greatly improved, which is beneficial to early detection of diseases.
