Target CD4+ T cells in unpurified whole blood samples were labelled with anti-CD4 antibody-coated beads and driven through the microfluidic chip by gravity-driven slug-flow where they were recorded ...

The new microfluidic device uses a large number of tiny channels, about the width of a human hair, designed to quickly and efficiently separate blood cells by size in a process called controlled ...

allowing thermal cycling and magnetic bead operations to be done automatically. Droplets move within the cartridge, surrounded by air. The microfluidics technique also allows for volume reduction ...

The team incubated unpurified whole blood samples with beads coated with anti-CD4+ antibodies, which allowed them to bind specifically to CD4+ T cells in the sample. The sample was then passed through ...
