Nano Drugs And Their Safety

Nano drugs or nano medicine is the medical application of nanotechnology.

As defined by the Royal Society and Royal Academy of Engineering, “nanoscience” is the study of phenomena and manipulation of materials at atomic, molecular, and macromolecular scales, where the properties differ significantly from those at a larger scale and “nanotechnologies” are the design, characterization, production, and application of structures, devices, and systems by controlling shape and size at the nanometer scale. In recent years, great progress was achieved in making drugs own the characteristics of targeted and controlled release via nano technologies. Nano drug is an important product of the rapidly developing nano technologies in biology and medicine field. The drug is usually made from natural polymer material. The main advantage is that it can effectively improve stability of clinical drug, improve patients' drug absorption capacity, and thus effectively improve targeting of drugs and drugs nature, which can effectively extend action time of drug, then effectively improve clinical effect of the drug and minimize toxic and side effects of the drug. Types of Nano-Structures.

Polymeric nanoparticles:

Polymeric nanoparticles (colloidal solid particles with a size range of 10 to 1000nm) have a matrix architecture composed of biodegradable and biocompatible polymers of synthetic or natural origin.
