Immobilised chemiluminescence reagent. (Inorganic Chemistry).(Brief Article)

Detection based on the chemiluminescent reactions of tris(2,2'-bipyridyl)ruthenium(II) is established yet much of this expensive reagent is wasted in flow systems. Efforts have been made to immobilise this reagent in a number of ways, but Barnett et at (Analyst 2002, 127. 455) report a simple way to immobilise such a reagent to silica particles. The reagent. (4-[4-(dichloromethylsilanyl)-butyl]-4'-methyl-2,2'bipyridyl)bis(2,2' -bipyridyl)ruthenium(II) was covalently immobilised onto silica particles that could be packed into glass …
