According to the irreversible thermodynamic coupling flow theory, Katchalsky and Curran [11] considered that, under static conditions, thermodynamic force on the semipermeable membrane is in balance with the sum of mechanical friction forces produced by various components of solution in the membrane.
Even so, it has to be kept in mind that in all groups a semipermeable membrane was used for GBR purposes.
Bacteria or endotoxin can also enter the sterile saline-primed dialysis circuit either through direct contact with a contaminated surface or through the semipermeable membrane of a dialyzer.
Permeation is the movement of molecules by diffusion from high concentration to low concentration through a semipermeable membrane. Only those molecules that are small enough to fit through the membrane pores are able to move through the membrane and reach equilibrium with the entire volume of solution like 3 kDa dextran in this system (Figure 7(d)).

The elementary osmotic pump (EOP) consists of an osmotic core with the drug, surrounded by a semipermeable membrane with a delivery orifice.
A semipermeable membrane between the cell types in the co-culture system prevented direct cell-to-cell contact but allowed secreted factors to pass freely between cells.
To prove the feasibility of their technology, the authors used an in vivo murine model to measure markers of myocardial injury (myoglobin, creatine kinase isoenzyme MB, and cardiac troponin I) that involved subcutaneous placement of a sensor containing the nanoparticles within a semipermeable membrane placed in the animal's flank.
