A facile method to prepare monodisperse speckled colloidshas beendeveloped via one-step seeded polymerization from noncross-linkedlatex particles. It was found that both cross-linking agents in theadded monomer mixture and charged initiation species are essentialfor the formation of speckles on composite latex particle surfacein seeded polymerization. The size and number density of speckleson the surface are tunable by adjusting the concentration of surfactant.A possible mechanism for the formation of such speckled colloids hasbeen proposed based on a series of control experiments. Speckled colloidalparticles were used as substrates for the adsorption of tobacco mosaicvirus, and a much stronger adsorption was observed compared to smoothparticles, implying a potential application of these speckled particlesin virus collection and more.
