The widely employed electroanalytical technique of adsorptive stripping voltammetry (AdsSV) is critically assessed and evaluated at a wide diverse range unmodified nano-particle modified carbon electrodes using the analyte fipronil as paradigmatic case. generic performances are investigated compared with revealing similar LOD values pointing to intrinsic limitations AdsSV arising from non-indep...

Inactivation of redox enzymes and the loss enzyme’s material from its adsorbed film on electrode surface are events that have similar outputs when studied under conditions protein-film voltammetry. In current work, we present a series novel theoretical results cyclic staircase voltammetry clearly reveal how to distinguish between these two events. Theoretical model elaborated in this work compr...

BACKGROUND Given that Δ(9)-tetrahydrocannabinol, the active constituent of cannabis, has been shown to greatly reduce driving ability, thus being linked to many drug driving accidents, its reliable detection is of great importance. RESULTS An optimised carbon paste electrode, fabricated from graphite powder and mineral oil, is utilised for the sensitive detection of Δ(9)-tetrahydrocannabinol ...
