Process for preparing magnetic composite for the purpose of surface enhanced Raman spectroscopy, magnetic composite per se and use thereof

摘要

Relates to a process for preparing a magnetic composites for surface enhanced Raman spectroscopy, when the aqueous dispersion of polystyrene particles with a magnetic core adds silver and / or auric and / or Zlatná salt and / or particles of silver and / or gold, and finally optionally a solution of reducing agent, wherein the magnetic composite optionally further comprises streptavidin. The solution subject is also a magnetic composite for purposes of surface enhanced Raman spectroscopy, obtainable by the method according to the present solution, which contains a composite of polystyrene microspheres with the magnetic core particles and the gold and / or silver. Further subject of the solution using a magnetic composites for surface enhanced Raman spectroscopy.
