RT Journal Article SR Electronic T1 Interferometric Fluorescent Cross Correlation Spectroscopy JF bioRxiv FD Cold Spring Harbor Laboratory SP 671016 DO 10.1101/671016 A1 Ipsita Saha A1 Saveez Saffarian YR 2019 UL http://biorxiv.org/content/early/2019/06/13/671016.abstract AB We present a method utilizing single photon interference and fluorescence correlation spectroscopy (FCS) to simultaneously measure transport of fluorescent molecules within aqueous samples. Our method, within seconds, measures transport in thousands of homogenous voxels (100 nm)3 and eliminates photo-physical artifacts associated with blinking of fluorescent molecules. A comprehensive theoretical framework is presented and validated by measuring transport of quantum dots, associated with VSV-G receptor along cellular membranes as well as within viscous gels.
