Droplet based measurement of specific capacitance and interfacial tensions

摘要

Disclosed are methods and apparatus for determining the properties of artificial membranes (e.g., artificially prepared lipid bilayers and biomimetic membranes comprising amphiphilic copolymers). Multiple physical properties of the membranes can be determined via a combination of electrical and optical measurements. The optical and electrical measurements can be determined using a single apparatus, which can also be used to prepare the artificial membrane. Methods are also disclosed for determining the effects changes in the composition of the artificial membrane, such as the addition of a drug or a change in lipid content.
