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.
Claims21
A method for detecting a fingerprint comprising:
- contacting an area comprising a hydrophobic mass with an agent comprising hydrophobic silica particles, wherein the hydrophobic mass comprises the fingerprint, and wherein the silica particles comprise a visualization or imaging agent;
- and
- visualizing and/or imaging the fingerprint.
