These techniques all share the same advantages when ported on-chip: reagent volumes are reduced, therefore minimising cost, and the tiny size of each reaction chamber allows massive parallelisation of the experiment, enabling high-throughput screening. More specifically, ''in vitro'' gene synthesis becomes affordable at this scale. Our MITOMI chip contains 768 wells, all visible in one frame, which allowed us to quantify affinity of hundreds of protein-DNA combinations in a single experiment. The small channels also allow fine control over reaction conditions. Most soluble reagents can be used, including DNA, proteins, molecule libraries, and so on - allowing much creativity in experimental design.
