5.2 Drug Delivery System
5.2.1 Advantage of Nano-drug delivery system
By diagnosis, and for treatment, we need enhanced drug delivery system. Drug delivery system of these days is just eat and let it flow through the body. It is not good at efficiency. Because the digestive system sometimes digest and remove the drug before it reaches to the target.
For enhancing the efficiency of drug
Nanoparticles present possible dangers
- due to the high surface to volume ratio
pass through cell membranes in organisms
Smaller nanoparticles evinced increased cytotoxicity.
Self-assembly :
process that disordered system of components forms an organized structure or pattern
The device is switched on - >
the pump pushes ions across the lipid membrane,
Reason for the increasing proportion of older people
The improved care of expectant mother and newborn infants has “reduced the infant mortality rate”
New drugs, better sanitation, and other medical advances have “increased life expectancy”
: Male 58.7>75.6, Female 65.6>83.3 (1970>2008)
Especially, in Korea
The birthrate is rapidly declining >>
