organic light emitting diode(OLED)
LED's emissive electroluminescent layer is composed of a film of organic compounds.
This layer of organic semi-conductor material is formed between two electrodes, where at least one of the electrodes is transparent.
OLED can be used in many display devices.
Active matrix OLED has an integrated electronic backplane made from thin film transistor

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
Dialysis
What is dialysis?
Dialysis is a membrane process where solutes (MW~<100 Da) diffuse from one side of the membrane (feed side) to the other (dialysate or permeate side) according to their concentration gradient. First application in the 70’s.
General Principles
Separation between solutes is obtained as a result of differences in diffusion rates.
These are arising from differe
