Abstract
AbstractThe binding of Co(bpy)2dppz3+ to calf thymus DNA was investigated by using absorption and emission spectroscopy, DNA melting techniques, cyclic voltammetry, viscosity and electro phoresis measurements, where bpy is 2,2′‐bipyridyl, dppz is dipyrido[3,2‐a:2′,3′‐c] phenazine. The binding compound shm absorption hypochromicity, fluorescence enhancement, and increasing of DNA melting temperature and the specific viscosity. CV measurement shows the shifts in oxidation‐reduction potential and change in peak current with addition of DNA. The compound ie also shown to be more efficient photosensitisers for strand breaks in plasmid DNA.
