Over the recent years, we have significantly advanced flow control on centrifugal microfluidic “lab-on-a-disc” platforms. These novel, event- and pulse-triggered valving schemes establish logical, Boolean-type relationships such as AND / OR which are well familiar to large-scale integrated electronic circuits that are the backbone of our modern, ubiquitous gadgets. Furthermore, we established a fluidic “clock” which can time on-disc processes. As a result, the spin rate may essentially be freely programmed, e.g. to optimise conditions for on-disc sample preparation, on-board reagent storage and detection. Through these significant extensions of the centrifugal microfluidic toolbox, we have demonstrated higher-level integration and automation of various multi-step, multi-reagent, multi-parameter test panels implementing methods such nucleic acid amplification, immunoassays and cell counting.

In part one of "Microfluidics Adventures," brought to you by the Lutetium Project, Marie Boulez sets the scene and explains why it is so compelling to make products smaller, from a theoretical point of view. This first part of the three-part series will help you understand the physics concepts that are fundamental to microfluidics.WATCH NOW
Only 17% of the English-language biographies on Wikipedia are about women – but the statistic won’t stay that low for long if Dr Jess Wade has her way. A passionate advocate for diversity in science, Jess balances her work as an award-winning physicist at Imperial College London with her role as a ‘Wikipedian’, creating and uploading the biographies of underrepresented groups in science.WATCH NOW
