<p>Apparatus for characterizing molecules comprises a barrier (10, 14) between a first volume (24) and a second volume (32), the barrier having a pore (18) through it, a pair of electrodes (36, 38) arranged to generate an electrical potential difference between the first and second volumes to drive molecules from the first volume to the second volume, and optical sensing means (44, 40, 42) arranged to detect light from the pore thereby to detect passage of a molecule through the pore.</p> |
