With the rapid development of nanotechnology, there are many methods, such as electron beam printing, focused ion beam printing and the others, which can prepare nanoparticles with controllable shape and size. The prepared nanoparticles can be formed into a variety of nanostructures including spherical, rod-shaped, flakes-shaped, shell, tetrahedron, hexagon, star, prism and the others. Nanoprisms is a kind of nanomaterial with prismatic morphology, which is composed of nano - flakes. Nanoprisms have excellent optical and chemical properties and have wide potential applications in many fields. The research about nanoprisms starts late, which is a new material subject.
Based on the excellent properties, nanoprisms have a wide range of applications in the fields of biological imaging, biosensor, biomolecule and inorganic ion detection, optical sensor and the others.

According to the composition, nanoprisms can be divided into silver nanoprisms, gold nanoprisms and the others.
