The prefix “nano” is a Greek word which means “dwarf ”.
The word “nano” means very small or miniature size.
Dendrimers: Dendrimers are hyper branched, tree-like structures.
It contains three different regions: core moiety, branching units, and closely packed surface (Figure 5).
It has globular structure and encloses internal cavities. These are used for long circulatory, controlled delivery of bioactive material, targeted delivery of bioactive particles to macrophages and liver targeted delivery.
Classification of Nano Materials Nano materials can be classified dimension wise into following categories: Classification Examples • Nano rods, nano wires have dimension less than 100 nm.Anna Pratima Nikalje Department of Pharmaceutical Chemistry Y.

Nano scale and Nanostructures The nano scale is the place where the properties of most common things are determined just above the scale of an atom.Nano scale objects have at least one dimension (height, length, depth) that measures between 1 and 999 nanometers (1-999 nm) (Figure 1).Liposomes: These have been extensively explored and most developed nano carriers for novel and targeted drug delivery due to their small size, these are 50-200 nm in size.When dry phospholipids are hydrated, closed vesicles are formed (Figure 4).Applications of nano technology in tuberculosis treatment, the clinical application of nanotechnology in operative dentistry, in ophthalmology, in surgery, visualization, tissue engineering, antibiotic resistance, immune response are discussed in this article.Nano pharmaceuticals can be used to detect diseases at much earlier stages.
