Celestine Blue

Celestine Blue is a electroactive indicator in DNA biosensors. Celestine Blue is strongly adsorbed on the spinel phases and CNT (carbon nanotubes), facilitates dispersion, acts as a capping agent and allows for the fabrication of spinel decorated CNT. Celestine Blue is an efficient charge transfer mediator, which allows for significant improvement of capacitive behavior. TiO2 nanoparticles doped with Celestine Blue can be used as a label in a sandwich immunoassay for the hepatitis C virus (HCV) core antigen[1][2][3].
