ABSTRACT:
A filter and filtering apparatus for measuring the deformability of a blood cell passing through a flow passage formed as a space between a surface of a groove formed in a first substrate and a surface of a second substrate with which the groove is sealed. The filtering apparatus includes electrodes mounted at the inlets and outlets of the flow passages, or optical elements to enable cell deformity measurements.
