Teorell's fixed charge theory for membrane ion permeability was utilized to calculate specific ionic permeabilities from measurements of membrane potential, conductance, and specific ionic transference numbers. The results were compared with the passive ionic conductances calculated from the branched equivalent circuit membrane model of Hodgkin Huxley.(More)
Hollow fiber membranes are enjoying widespread use as barrier materials in many implanted applications. In order to predict in vivo device behavior, it is important to understand and quantify the changes to the membrane and to the tissue immediately surrounding it that occur following implantation. We have considered a range of commercially available hollow(More)

A mathematical model was developed to describe the dose-response relationship of an optical glucose sensor. The basis for glucose detection is the reversible competitive displacement of a ligand from a receptor protein with specific binding sites for certain carbohydrates. Detection of glucose is based on measurements of the change in fluorescent lifetime(More)
