Abstract: The invention relates to a process of fabricating a beaded path on the surface of a substrate, the process comprising: preparing a dispersion of particles in a liquid; supplying the prepared dispersion to at least one electrically conductive microcapillary in a continuous manner; forming and maintaining a convex meniscus of the dispersion at the outlet end of the microcapillary positioned above and/or below the surface of a substrate; applying alternating voltage to the microcapillary so that a beaded structure is formed between the dispersion meniscus and the surface of the substrate; and moving the microcapillary relative to the substrate and/or the substrate relative to the microcapillary so as to deposit the particles of the formed beaded structure on the surface of the substrate and simultaneously rebuild the beaded structure formed between the dispersion meniscus and the surface of a substrate.
