ABSTRACT:
A method and apparatus for measuring the presence or absence of interaction between at least a first and second material of interest by measuring osmotic pressure changes in an osmotic cell. Changes in osmotic pressure are determined by measuring the amount of compression exhibited by a compressible, semi-permeable material positioned in the cell.
