TY - JOUR T1 - A wireless centrifuge force microscope (CFM) enables multiplexed single-molecule experiments in a commercial centrifuge JF - bioRxiv DO - 10.1101/060269 SP - 060269 AU - Tony Hoang AU - Dhruv S.

Here we developed a low-cost and selfcontained CFM module that works directly within a commercial centrifuge, greatly improving accessibility and ease of use. Our instrument incorporates research grade video microscopy, a power source, a computer, and wireless transmission capability to simultaneously monitor many individually tethered microspheres. We validated the instrument by performing single-molecule force shearing of short DNA duplexes. For a 7 bp duplex, we collected over 1000 statistics of force dependent shearing kinetics from 2 pN to 12 pN with dissociation times in the range of 10-100 seconds. We extended the measurement to a 10 bp duplex, applying a 12 pN force clamp and directly observing single-molecule dissociation over an 85 minute experiment. Our new CFM module facilitates simple and inexpensive experiments that dramatically improve access to singlemolecule analysis. ER -
