Miniaturized magnetic bead-actuators for force-clamp spectroscopy-based single-molecule measurements.
Ultramicroscopy(2020)
摘要
•We introduce a new force-clamp method for AFM using miniaturized magnetic beads as manipulators.•The new method improves the stability of the AFM system.•The new method enables force-clamp experiments without an active feedback.•Automatic digital controller enables high data throughput.
