Computation of the electrical double layer properties of semipermeable membranes in multicomponent electrolytes
A methodology is presented for calculating of the surface potential, Donnan potential, and ion concentration profiles for semipermeable microbial membranes that is valid for an arbitrary electrolyte composition. This model for surface potential, Donnan potential, and charge density was applied to recently reported experimental data for gram-positive bacteria, including Bacillus brevis, Rhodococ...
متن کاملApplication of Semipermeable Membranes in Glucose Biosensing
Glucose biosensors have received significant attention in recent years due to the escalating mortality rate of diabetes mellitus. Although there is currently no cure for diabetes mellitus, individuals living with diabetes can lead a normal life by maintaining tight control of their blood glucose levels using glucose biosensors (e.g., glucometers). Current research in the field is focused on the...
متن کاملFocal chemotherapy of brain tumours using semipermeable membranes.
Semipermeable silastic rubber membranes can be used to diffuse focally a variety of chemicals including antitumour drugs. Of the eight drugs tested, in vitro tests showed the best diffusion with dactinomycin, mithramycin, and oncovin, and the poorest diffusion with bleomycin, fluorouracil, and thiotepa. Biological testing was performed with mithramycin, dactinomycin, and oncovin using tissue cu...
متن کاملDiscontinuous Galerkin Methods for Mass Transfer through Semipermeable Membranes
A discontinuous Galerkin (dG) method for the numerical solution of initial/boundary value multicompartment partial differential equation models, interconnected with interface conditions, is presented and analyzed. The study of interface problems is motivated by models of mass transfer of solutes through semipermeable membranes. More specifically, a model problem consisting of a system of semili...
متن کاملThe Electrical Properties of Synthetic Membranes
By the addition of n-butyl bromide to a 1:19 copolymer of 4-vinylpyridine and styrene, water-insoluble, strong polyelectrolytes can be prepared. The addition of a hydrocarbon plasticizer permits the casting of flexible films in which large polycations are immobilized but in which bromide ions (or other small anions) are free to move. Electrical measurements on these membranes showed that they c...
