Photo-controllable percolation of decorated nanoparticles in a nanopore: molecular dynamics simulation study

By means of molecular dynamics simulations we study formation of the wall-to-wall     percolation cluster in the solution of decorated nanoparticles in a pore. The model takes into account photo-switching between unpolar \trans\ and polar \cis-isomers of azobenzene. This leads to either colloidal dispersion of the particles or their aggregation     in a polar solvent. The dynamics of percolation cluster formation is analysed by applying a pulse-like illumination.
