The magnetic tweezer is a single-molecule instrument that can apply a constant force to a biomolecule over a range of extensions, and is therefore an ideal tool to study biomolecules and their interactions. However, the video-based tracking inherent to most magnetic single-molecule instruments has traditionally limited the instrumental resolution to a few nanometers, above the length scale of single DNA base-pairs. Here we have introduced superluminescent diode illumination and high-speed…

Camera-based three-dimensional real-time particle tracking at kHz rates and Ångström accuracy
TLDR
This work demonstrates that camera-based imaging can provide a similar performance for all three dimensions of particle tracking with Ångström accuracy as laser detection through photodiodes, and provides a simple and robust way for high-resolution tweezers experiments using multiple particles at a time.

Skewed Brownian Fluctuations in Single-Molecule Magnetic Tweezers
TLDR
This work demonstrates that nearby surfaces and the non-linear elasticity of DNA can skew the distribution, leading to inaccurate position measurements which significantly affect the extracted DNA extension and mechanical properties, and develops a simple, robust and easily implemented method to correct for such mismeasurements.
Combined Magnetic Tweezers and Micro-mirror Total Internal Reflection Fluorescence Microscope for Single-Molecule Manipulation and Visualization.
TLDR
This chapter provides a simple method to calibrate the evanescent wave penetration depth via supercoiling of DNA with a fluorescent nanodiamond-labeled magnetic bead and a complementary method employing a surface-immobilized fluorescent Nanodiamond.
