Abstract:On microarrays the transport of the target molecules towards the spots only occurs by molecular diffusion. As a result, microarray analyses require overnight incubation and are highly inefficient in terms of capture rate and detection limit. To overcome this diffusion limitation, several solutions have already been proposed: electrokinetic flows, ultra-sound mixing, pump-around systems, etc…. The present study demonstrates how DNA microarray analysis is enhanced by miniaturization. Only a small sample volume (
