Method for deposition of nanoparticles on solid substrates and surface covered by this method

  • Summary:

    The invention comprises a method for controlled deposition of a monolayer of nanoparticles (NPs) on a solid surface, featuring the Langmuir-Blodgett technique. A mixture of NPs and a liquid crystaline (LC) compound forms a 2D network when spread on water surface and can be subsequently transferred onto a solid substrate. Adjustment of the compression of the formed film allows for facile control over the mean size of the mesh domains. A desired degree of coveridge of the surface with the NPs can be achieved by tuning the composition of the utilized NP/LC mixture. If gold NPs are used, the obtained structure can be used in the Chemical Vapor Deposition procedure to grow GaN nanorods only in places where the NPs were deposited.
