Efficient AC electrothermal flow (ACET) on-chip for enhanced immunoassays

Martinus Gijs, Diego Gabriel Dupouy, Muaz Salama Abdelmonem Draz

Biochemical reaction rates in microfluidic systems are known to be limited by the diffusional transport of reagents, leading often to lowered sensitivity and/or longer detection times in immunoassays. Several methods, including electrically powering electr ...

Microfluidic-integrated vertical electrodes employed in impedance-based cytometry

Enrica Rollo

During the last decades, the growing interest for single-cell analysis has led to the creation of a number of microfluidic and lab-on-a chip (LOC) platforms for characterizing cellular samples. In that context label-free based platforms are minimally invas ...
