Abstract
We report on fast biomolecules separation using three-dimensional nanowires structure devices. The three-dimensional nanowire structure can be synthesized and embedded in microchannel by Vapor-Liquid-Solid (VLS) technique. We decorate Au catalyst along the nanowires by DC sputtering and growth nanowire as a cycle to prepare the branch of the nanowire structure. This technique allows researchers to control the pore size of the three-dimensional nanowires by increasing the number of growth time. We separated small DNA molecules mixture (50-100 bp) within 35 seconds and proteins mixture (20-66 kDa) within 2.5 seconds under DC electric fields.
