Although around 90 years have passed since Richards and Loomis developed the first experiments in sonochemistry, ultrasound is still awakening interest in the scientific community, in particular in the Analytical Chemistry field, as a result of the high number of benefits achieved, which are also in accordance with Green Analytical Chemistry principles. In the last years, and among the different reported applications, an important number of works have arisen devoted to the synthesis of new materials (specially nanomaterials), to the development of sonoelectroanalytical sensors or to new spectroscopic approaches, among others. Efforts are also being made to try to understand the real mechanism of such applications. This review article is aimed at providing a general overview of the different applications of ultrasound in Analytical Chemistry, also briefly highlighting its fundamentals and traditional applications, with a special emphasis on the most recent and challenging works that are still in the horizon of its near future.
