Three-Dimensional Writing of Conducting Polymer Nanowire Arrays by Meniscus-Guided Polymerization.
The group of Prof. Giorgio Margaritondo 
(LPRX - X-Ray Physics Laboratory) specifically demonstrate well-defined dense arrays of various freestanding nanocomponents with controlled radius down to ∼50 nm: straight wires, nanowires with variable radius, branches, and bridges.
