Optical traps are an important tool for research in the field of single molecule biophysics. Recent
advances in optical trapping have extended their functionality from simple linear manipulation and
measurement of forces, to now the ability to rotate objects and measure torques. This mini review
summarizes these recent developments of the optical trap as a tool to apply and measure torque in
biophysical applications.
