Description

2,7-Dinitro-9-fluorenone was used to develop sensor for determination of submicromolar concentrations of selected genotoxic nitro compounds using mercury meniscus modified silver solid amalgam electrode coupled with direct current voltammetry or differential pulse voltammetry. It was used to study mechanism of generation of spontaneous and mutation-induced deletion revertants of hisG428 inSalmonellatester strain TA102.
