From: Optofluidic analysis system for amplification-free, direct detection of Ebola infection
On-chip target preconcentration.
(a) Particles to be concentrated: target oligomers are bound to pull-down recognition sequence on magnetic microbeads; molecular beacons specifically bind to target and cause beads to fluoresce; (b) particle fluorescence counts detected on ARROW chip before preconcentration step and (c) after preconcentration on automaton. A 335x concentration increase is observed.
