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
투석 막의 한쪽 편으로 흘려보내면서, 동시에 막 반대편에서는 투석액을 혈액과 반대 방향으로 흘려보낸다. 혈액중의 노폐물은 membrane을 통하여 이 투석액 속으로 들어가므로 혈액의 정화가 이루어진다. 정화된 혈액은 그대로 관을 통하여 환자의 몸으로 되돌려 보내진다.

Contact angle goniometry(CAG):
- examine hydrophilicity or hydrophobicity of a surface
X-ray photoelectron spectroscopy (XPS):
- testify bond types / define chemical species and oxidation states
- demonstrate that the film is of single monolayer thickness.
Fourier-transform infrared spectroscopy (FT-IR):
- measure the
keratinocytes ("satellitosis") [9]. As the lesions progress, frank subepidermal vesiculation develops, with full thickness epidermal necrosis.
