摘要

A simple and low cost method of producing sealed arrays of laterally ordered nanochannels interconnected to microchannels of tunable size, over large surface areas, is disclosed. The method incorporates DNA combing and subsequent imprinting. Associated micro and macroscale inlets and outlets can be formed in the same process or manufactured later in low cost, non-cleanroom techniques. The techniques embrace two procedures, generating DNA nanostrands and translating these strands into nanoscale constructs via imprinting. Devices incorporating the novel arrays have a first microchannel, a second microchannel and a nanochannel that is substantially linear and which defines an axis. The nanochannel is connected at its open ends to the microchannels, which are aligned along the axis. Methods for precise dose delivery of agents into cells employing the devices in nanoelectroporation methods are also disclosed.
