Visual detection of dopamine and monitoring tyrosinase activity using a pyrocatechol violet-Sn4+ complex.
In this study, the ensemble of pyrocatechol violet and Sn(4+) was used for dopamine detection in a neutral aqueous solution with high selectivity and sensitivity. The detection course showed three color changes, which could be observed by the naked eye. We also demonstrated that this ensemble can be used to monitor tyrosinase activity.
