Single entity electrochemistry of collision (SEEC) is an emerging electrochemical method with the great potential for ultra-sensitive analysis applications. Here, the possibilities and challenges of SEEC in sensing are discussed. The analytical characteristics of the collision-based detection method, such as sensitivity, detection range, the limit of detection, signal-to-noise ratio, and selectivity, are examined. Factors affecting these parameters and strategies to improve them are discussed. Potential target analytes in environmental and bioanalytical applications are overviewed based on the reported up to date literature. Finally, challenges and limitations currently preventing real-life applications of the method are highlighted.
