| Summary: | This review highlights recent advances made towards improving sonoelectroanalysis with an emphasis on applications where conventional electrochemical methodologies often fail. It is shown that: 1) the significantly increased mass transport regime under insonation very considerably enhances the sensitivity in comparison to what would be obtained under quiescent conditions and, in particular, 2) cavitational activity at the electrode solution interface provides depassivation in highly 'dirty' media or in the presence of undesirable surface active species and so can preserve quantitative electrode activity in complex, real world samples so removing the requirements for sample pretreatment which has hitherto limited the wider applications, for example, of stripping voltammetry.
