Fluorescence Correlation Spectroscopy: A Review of Biochemical and Microfluidic Applications

Research output: Contribution to journalArticlepeer-review


Over the years fluorescence correlation spec- troscopy (FCS) has proven to be a useful technique that has been utilized in several fields of study. Although FCS initially suffered from poor signal-to-noise ratios, the incorpo- ration of confocal microscopy has overcome this drawback and transformed FCS into a sensitive technique with high figures of merit. In addition, tandem methods have evolved to include dual-color cross-correlation, total in- ternal reflection fluorescence correlation, and fluorescence lifetime correlation spectroscopy combined with time-correlated single-photon counting. In this review, we discuss several applications of FSC for biochemical, micro- fluidic, and cellular investigations.
