Abstract

A new concept and device for forming a stationary gradient with flow, yet without shear, is presented. A microfluidic probe (MFP) with four apertures is immersed in a fluid and placed atop a substrate. Pairwise injection and aspiration creates a stagnant point at the center of the probe where a chemical gradient can be formed. The gradient can be shaped by adjusting the flow rate and moved across the surface with the MFP. A prototype and proof of concept simulations and experiments are presented.
