Regiospecific assembly of gold nanoparticles around the pores of diatoms: toward three-dimensional nanoarrays.
The templated growth of gold nanoparticles in 3D arrays within the nanopores of unicellular diatoms involves pretreament of the skeletons with poly(vinylpyridine) which has a unique dewetting property. This self-assembly provides a nanochemical analogue of lithography for engineering complex nanostructures. The process can be universally applied to the many types of diatom skeletons which vary in size and structure.
