Nano Pharmaceuticals

Nano pharmaceuticals are colloidal particles of 10 to 1,000 nano meters (1 micron) in size. They are widely used in drug delivery. Nano pharmaceuticals are diverse both in their shape and composition and often offer an advantage as compared to their “bulk” counterparts primarily because of size. As a result, the properties of nano materials are fundamentally different from those of their macroscopic/ bulk analogues due to an increased surface area and quantum effects. As a particle’s size decreases, a greater proportion of its atoms are located on the surface relative to its core, often rendering the particle more reactive and more soluble in water.
