In this manuscript, we report the development of a rapid and facile optic sensor for highly sensitive and selective detection of cobalt ions (CII)). The detection strategy was based on the specific silver nanoparticle-glutathione interaction and later on secondary interaction of this structure with cysteine and CII) ion. The interaction of these structures creates a new absorption band in the UV region. The intensity change of this band can be correlated by CII) ion concentration. The addition of cysteine decreases the Surface P
