Abstract:

Single-cell analysis enables more accurate acquisition of biological information and avoids the loss of single-cell heterogeneity features from averaging analysis, which is essential for studies to elucidate cell metabolism and signaling pathways. Electrochemical analysis techniques based on nanoelectrodes are widely used in single-cell analysis because of their high selectivity, high sensitivity and high spatiotemporal resolution. In this review, the latest research progress of the quantitative analysis of intracellular biomolecules in single cells using nanoelectrodes is reviewed. Moreover, its application in biological research and the challenges are introduced.
