METHOD AND APPARATUS FOR MEASURING CHANGES IN CELL VOLUME

摘要

A method and apparatus for measuring changes in cell volume generally includes introducing cells into a chamber having a volume between 2 and 100 times the volume of the introduced cell. A first electrically conductive extracellular fluid is introduced into the chamber and a current is applied. The current flow is measured. The first fluid is exchanged with a second electrically conductive extracellular fluid and a current is applied. The current flow is measured. The first current flow result and the second current flow result are used in conjunction with known current flows to monitor changes in the volume corresponding to fluid flow between the cell and an extracellular fluid.
