  • Increased particle stability in a wide range of solvents
  • Versatile conjugation surface for attaching functional groups or creating hydrophobic or fluorophillic surfaces
  • Nanoporous structure allows low molecular weight molecules to be loaded into the shell
Amine-Functionalized Silica Learn more +
  • Positively charged silica colloids and silica-coated nanoparticles
  • Useful for binding studies, conjugation with carboxyl-containing molecules through EDAC coupling, or binding to dyes and molecules with isothiocyanate (ITC) or amine-reactive esters
  • Many custom coatings are available to provide specific functionality at the particle surface or create particles compatible with different solvents or composites
