A device with femtoliter-scale chambers and controlled reaction initiation was developed for single-molecule enzymology. Initially separated substrate and enzyme streams were rapidly mixed in a microfluidic device and encapsulated in an array of individual microreactors, allowing for enzyme kinetics to

A novel assay of single-cell exogenous beta-galactosidase activity in Saccharomyces cerevisiae has been developed. Intracellular fluorescence due to the hydrolysis of resorufin-beta-D-galactopyranoside attains a steady state between production of resorufin and its subsequent leakage from the cell. The cells are
