PPT-Magnetic Torque Tweezers: measuring

torsional stiffness in DNA and RecA DNA filaments Lipfert J Kerssemakers J W Jager T amp Dekker N H What are Magnetic Tweezers Magnetic tweezers are a powerful singlemolecule technique that can be used to apply stretching forces and torques to biological molecules tethered between a surface and . In addition magnetic fields create a force only on moving charges The direction the magnetic field produced by a moving charge is perpendicular to the direction of motion The direction of the force due to a magnetic field is perpendicular to the dir All rights reserved This tip sheet was developed in conjunction with the Great Trays TM Partnership dap with permission by ina Ba no inda Die an and sk ey from hn al ta tool art of Io old tar le nu at in 20 Io Nu trition Proj Io De ar me of Edu atio . generation. in . s. uperparamagnetic. . particles.
