Geometric Flow Control Lateral Flow Immunoassay Devices (GFC-LFIDs): A New Dimension to Enhance Analytical Performance
Geometric flow control analysis of laser configured membranes. (a) Flow front displacement of GFC-LFIDs (, l, 45°, 45°) during 30 s interval recorded at 100 ms resolution as a function of the constriction length (l) and width () for fixed = = 45°. (b) Flow front displacement of GFC-LFIDs (0.4, 0.8 mm, 2 mm, , ) during 30 s interval recorded at 100 ms resolution as a function of the constriction and between 0 and 75°, for constants and . (c) Flow front displacement at constant constriction width, angles, and length for different locations along the flow axis x.
