General description

Tris(2,2′-bipyridyl)dichlororuthenium hexahydrate (RTDP, Ru(BPY)3) is an oxygen sensitive fluorescent dye.

Application

RTDP was used to measure the oxygen concentration in a microfluidic chip. A new hybrid material for oxidase based biosensors was prepared by combining Wells–Dawson K7[H4PW18O62]·18H2O (PW18) and RTDP. Silica nanoparticles doped with RTDP render them fluorescent, radio opaque and paramagnetic.
