The Microfluidic Probe: Operation and Use for Localized Surface Processing

Cecile M. Perrault¹, Mohammad A. Qasaimeh¹, David Juncker¹

¹Department of Biomedical Engineering, McGill University

In this video we present the microfluidic probe¹ (MFP). We explain in detail how to assemble the MFP, mount it atop an inverted microscope, and align it relative to the substrate surface, and finally show how to use it to process a substrate surface immersed in a buffer solution.

We demonstrate a snap chip technology for performing cross-reactivity-free multiplexed sandwich immunoassays by simply snapping two slides. A snap apparatus is used for reliably transferring reagents from microarray-to-microarray. The snap chip can be used for any biochemical reactions requiring colocalization of different reagents without cross-contamination.
