Four-color alternating-laser excitation single-molecule fluorescence spectroscopy for next-generation biodetection assays.
BACKGROUND Single-molecule detection (SMD) technologies are well suited for clinical diagnostic applications by offering the prospect of minimizing precious patient sample requirements while maximizing clinical information content. Not yet available, however, is a universal SMD-based platform technology that permits multiplexed detection of both nucleic acid and protein targets and that is suit...
متن کاملFluorescence-aided molecule sorting: analysis of structure and interactions by alternating-laser excitation of single molecules.
We use alternating-laser excitation to achieve fluorescence-aided molecule sorting (FAMS) and enable simultaneous analysis of biomolecular structure and interactions at the level of single molecules. This was performed by labeling biomolecules with fluorophores that serve as donor-acceptor pairs for Förster resonance energy transfer, and by using alternating-laser excitation to excite directly ...
متن کاملSingle-molecule, real-time measurement of enzyme kinetics by alternating-laser excitation fluorescence resonance energy transfer.
Using a single-molecule fluorescence method uniquely suitable for binding assay, alternating-laser excitation fluorescence resonance energy transfer (ALEX-FRET), we accurately measured the cleavage rate of 8-17 deoxyribozyme, an RNA-cleaving enzyme, at the single-molecule level in real time with a minimum consumption of samples, i.e., at least three orders of magnitude smaller than used in the ...
متن کاملBroadband single-molecule excitation spectroscopy
Over the past 25 years, single-molecule spectroscopy has developed into a widely used tool in multiple disciplines of science. The diversity of routinely recorded emission spectra does underpin the strength of the single-molecule approach in resolving the heterogeneity and dynamics, otherwise hidden in the ensemble. In early cryogenic studies single molecules were identified by their distinct e...
متن کاملAlternating-laser excitation of single molecules.
Single-molecule fluorescence spectroscopy addresses biological mechanisms and enables ultrasensitive diagnostics. We describe a new family of single-molecule fluorescence methods that uses alternating-laser excitation (ALEX) of diffusing or immobilized biomolecules to study their structure, interactions, and dynamics. This is accomplished using ratios that report on the distance between and the...
