Electrochemical analysis with the inherent advantages such as fast response, high sensitivity and operational simplicity has been widely investigated and developed in various research and application fields. To obtain analysis results of high sensitivity, good selectivity and long-term stability, considerable efforts have been made to develop a variety of nanomaterials to construct the high-efficient sensing interface, thus realizing the improvement of analytic performance. Aerogels derived from the preformed colloidal nanoparticles are a new class of porous material. They feature merits of low density, large specific surface area, good mechanical deformation, hierarchical porous structure, and high catalytic properties, which extends the structural characteristics as well as physicochemical properties of nanoscale building blocks to macroscale. These characteristics make the aerogels as superior sensing materials with high sensitivity, excellent selectivity, and fast response in electrochemical analysis. This mini-review mainly highlights the recent progress of novel aerogel materials in electroanalytical sensing, and emphasizes their applications in human health and environmental monitoring. Finally, its development prospects are discussed.
