Abstract
The present invention relates to an apparatus having a nanodevice for controlling the flow of charged particles in an electrolyte. Such apparatus comprises an electrolytic bath container divided by a polymeric foil into a first and a second compartment, wherein each compartment comprises an electrode connected to a voltage supply. Further the apparatus comprises at least one asymmetric pore forming a via hole through said foil, wherein said pore provides a narrow opening of a diameter in the range of several nanometers down to about one nanometer on a front side of said foil and a wide opening in the range of several ten nanometers up to several hundred nanometers on a back side of said foil. Further, the apparatus comprises an electrically conductive layer surrounding said narrow opening on said front side and a gate voltage supply connected to said electrically conductive layer on said front side of said foil controlling the flow of charged particles within said nanodevice from said first compartment to said second compartment vice versa. The invention further relates to a method for producing such a nanodevice.
