1. A method of screening test compounds for an effect on an interaction between components of a biochemical system, comprising;
- providing a substrate having at least two intersecting channels disposed therein, at least one of said at least two intersecting channels having at least one cross-sectional dimension in a range from 0.1 to 500 μ
m;
continuously flowing interacting components of a biochemical system in a first of said at least two intersecting channels;
flowing at least a first test compound from a second channel into said first channel whereby said first flowing test compound contacts said flowing components of said biochemical system; and
detecting an effect of said at least first flowing test compound on interactions between said continuously flowing components of said biochemical system.
