Biosensors and Analytical Detection

Single cell analysis is of great significance to biological and biomedical research. With recent development, lots of in situ amplification methods have been applied for imaging the spatial location of specific biomolecules in situ in single cells. In particular, RCA is a simple and efficient isothermal amplification method, which can locally amplify the fluorescent signal in situ. Due to the ability of detecting single molecules directly in cells and tissues, RCA has been widely used for illustrating many important biological processes. In this review, we summarize recent development of RCA-based method for single cell analysis and discuss their applications. Moreover, we emphasize the utilization of RCA for in situ sequencing, which is a very interesting and emerging research field.
