Magnetic tweezers are a powerful experimental technique used primarily in biophysics and molecular biology to manipulate and study the properties of individual biomolecules, such as DNA, RNA, and proteins. This technique utilizes magnetic fields to exert forces on magnetic beads that are attached to or associated with the molecules of interest. ### Key Components of Magnetic Tweezers: 1. **Magnetic Beads**: These beads, often coated with a biomolecule, serve as handles for manipulating the molecule of interest.
