Polymeric nanochannels have been fabricated using a cost-effective, fast, one-step method involving the collision of nanosized jets during electrospinning. The nanochannels had a uniform U-shaped cross-section, with a height below 100 nm and lengths around 1 mm. It was explained that the strength of the electric field had an important effect on the formation of the nanochannels. An adhesion test on the nanochannels using the lateral force mode of an atomic force microscope showed that the nanochannels formed by the jet impingement adhered well to a surface.
