Dialysis
Separation of substances in solution by means of their unequal diffusion through semipermeable membranes.
Dialysis
Dialysis is the separation of small solute molecules or ions (e.g., glucose, Na+, Cl-) from macromolecules (e.g., starch) by virtue of their differing rates of diffusion through a differentially permeable membrane.
We have developed a novel online microdialysis method at PNNL to remove salts, detergents, and buffers from such biological preparations as PCR and dideoxy sequencing mixtures. This has allowed for rapid and efficient desalting (e.g.
A dialysis machine which is used for people with kidney failure cannot differentiate between the useful and toxic molecules in the blood filtrate.
People with malfunctioning kidneys often have to go through a process called dialysis where they are hooked up to a machine that filters their blood.
The cell membrane, along with such things as dialysis tubing and cellulose acetate sausage casing, is such a membrane. The presence of a solute decreases the water potential of a substance.
A particular concern is the contamination of medical devices such as urinary catheters, hemodialysis equipment, and medical and dental implants. Biofilms that develop on these devices can increase the risk of patient infection.
Infection, environmental toxins such as mercury, and genetic disease can have devastating results by causing disruption of kidney function. Many kidney problems can be treated by dialysis, where a machine acts as a kidney.
