Abstract
A method of preparing hydrophobic silica particles includes the step of reacting together in a single step a mixture of silane ether monomers and organically modified silane ether monomers with a hydrolyzing agent. The method also includes producing hydrophobic silica microparticles and nanoparticles that can include dyes and/or magnetizable components. The silica nanoparticles can be used in the detection, visualization and/or analysis of latent fingerprints.
