Abstract
To slow down the speed of a biopolymer passing through a nanopore during electrophoresis to such a speed that enables a monomer sequence analysis to be performed. A biopolymer analysis device includes two tanksandeach capable of storing a solution containing a biopolymer and an electrolyte, a pair of electrodesand, a thin filmwith a nanopore, and a three-dimensional structuredisposed on the thin film. The three-dimensional structure has a void that can store a solution, and the void forms a flow channel, the flow channel being adapted to allow the solution to pass therethrough from the nanopore to a portion above the three-dimensional structure, and having on its surface a functional group capable of adsorbing the biopolymer. Thus, when a voltage is applied, the three-dimensional structure is not re-dispersed in the solution at least in the range of a hemisphere having the nanopore as the center and having a biopolymer trapping length r as the radius.
