Smaller than 100 nm nanomaterials are quite useful. Nanoparticles or single molecules are present. Nanoparticle-based functionality is not new. Older human societies utilised soot as a colourant, but more modern human populations employed colloidal gold particles, for example, in ruby-colored stained glass. Many nanotechnologies evolved in the recent several years, with several of which found on the market. While nanotechnology is often considered as cutting-edge, these substances are by no means novel from a chemical standpoint. Dendrimers are molecules with well-defined structures such as drug delivery vehicles and light-harvesting materials. Dendrimers can return to their centre of mass. resulting from this curvature, they are denser toward the centre shape-permanent polyphenylene dendrimers may be seen as individual nanosubstances using AFM. The density of the interior is smaller than that of the outside. because to the rigidity, excitation energy is unable to travel between them. Due to the limited mobility of the benzene rings, it means that the open space in the interior of the dendrimer remains constant and defined. Specificity in host–guest interactions allow the development of a nanoreactor, which resembles holes in inorganic materials like zeolites, which enable selective reactions to occur.
