| 1. A method for separation of molecules in at least one nanochannel comprising:
providing at least one nanochannel having charged nanochannel walls;
providing an electrolyte solution to the at least one nanochannel so that an electrical double layer forms near the charged
nanochannel walls;
introducing a mixture of at least two different types of molecules into at least one nanochannel;
allowing electroosmosis through at least one nanochannel to transport at least one of the at least two molecule types within
the nanochannel and to separate at least two different types of molecules within the nanochannel.
