What are the Techniques Used for Single Molecule Manipulation?
Several sophisticated techniques have been developed for single molecule manipulation:
Atomic Force Microscopy (AFM): AFM uses a sharp tip to interact with and measure forces on single molecules, providing high-resolution imaging and manipulation capabilities. Optical Tweezers: This method employs highly focused laser beams to trap and move individual molecules, allowing for precise manipulation and measurement of molecular forces. Magnetic Tweezers: Magnetic fields are used to control magnetic beads attached to molecules, permitting study of molecular interactions under varying forces. Scanning Tunneling Microscopy (STM): STM enables the manipulation of atoms and molecules on surfaces by using a conductive tip, which can also provide detailed topographical information.
