Electrochemical immuno-bioanalysis for carcinoma antigen 125 based on thionine and gold nanoparticles-modified carbon paste interface

A novel electrochemical immunosensor for the determination of carcinoma antigen 125 (CA125) was developed by means of immobilizing CA125 antibody (anti-CA125) on gold nanoparticles (Au) and thionine (Thi)-modified carbon paste interface. To avoid the leak of hydrophilic gold nanoparticles and thioni...
