The influence of stiction on the minimum spacing between suspended nanorods fabricated by femtosecond-laser-induced two-photon polymerization has been investigated. The minimum spacing is predicted based on a theoretical model calculating the adhesion length of a nanorod pair, which is in good agreement with the experimental results for suspended nanorods with feature size of around 200 nm. This is helpful for the polymerization of three-dimensional functional nanostructures.
