CPNs™ have many advantages over traditional dyes and probes

  • Extraordinary stability – 20 months, pH 2 – pH 10, up to 120°C
  • Excellent photostability – in cells and samples, they do not fade
  • Stable dispersion in solution – nano-colloidal system
  • Non-toxic – heavy-metal free, organic
  • Contains iron oxide – for magnetic manipulation
  • Various colours – including widely used red, yellow, green & blue, as well as IR
  • Familiar surface ligand chemistry – for attaching targeting biomolecules (Ab, oligonucleotides, streptavidin, etc.)
  • Storage at ambient temperatures – unless linked to a biological molecule, then store at 4°C
