    DNA sequencing in a lab-on-a-chip aims at providing cheap, high-speed analysis of low reagent volumes to, e.g., identify genomic deletions or insertions associated with genetic illnesses. Detecting single base-pair insertions or deletions from DNA fragments in the diagnostically relevant range of 150-1000 base-pairs requires a sizing accuracy of S < 10^-3, while only S < 10^-2 were reported. Here we demonstrate a sizing accuracy of S = 4 x 10^-4, thereby paving the way for the envisaged applications.
