Definition

Nanopharmacology can be defined as the  application of nanotechnology to the development and/or discovery of methods to deliver drugs. In this context a nanodrug can be a vector (nanovector) designed to deliver a pharmacological agent (drug).

The prefix "nano" originates from the word νάννος (Greek for dwarf). It refers to something small . The prefix is used for a unit of time or length, volume and it means one billionth of that unit. Thus, a nanometer (nm) is 10-9 meter.

The use of nanodrugs is to reduce the drug related side effects and improve its therapeutic  efficiency.

Dendrimers

 

 

 

 

From "dendros", tree in Greek. Man-made molecules that have a tree-like, branched shape; these regularly developing branches emanate from a core (hyper-branched molecules). The terms "arborols", and "cascade molecules" are also used but dendrimers is the best established.

Nanotechnology

 

Manipulation of  atoms and molecules in a precise, controlled manner.

The term “nanotechnology” was first used by Taniguchi et al in 1974

Reference: N. Taniguchi, On the basic concept of ‘nano-technology.’, Proceedings of the International Conference of Production Engineering, Society of Precision Engineering, Tokyo, Japan (1974).

 

 A formal definition for nanotechnology: “Nanotechnology is concerned with materials and systems whose structure and components exhibit novel and significantly improved physical, chemical, and biological properties, phenomena, and processes because of their small nanoscale size. Structural features in the ranges of approximately 10-9 to 10-7m (1–100 nm) determine important changes as compared to the behavior of isolated molecules (1 nm) or of bulk materials”. (Provided in the 1999 report of the Inter Agency Working Group on Nanoscience, Engineering, and Technology presented to the Office of Science and Technology Policy Committee on Technology)
