What Techniques are Used in Single Molecule Experiments?
Several advanced techniques are employed in single molecule experiments, including:
1. Atomic Force Microscopy (AFM): This technique uses a mechanical probe to measure forces between the probe and the sample, allowing for high-resolution imaging and manipulation of individual molecules.
2. Fluorescence Microscopy: This method uses fluorescent tags to visualize and track individual molecules in real time.
3. Optical Tweezers: This technique uses focused laser beams to manipulate single molecules with high precision.
4. Scanning Tunneling Microscopy (STM): This method involves scanning a sharp tip close to the surface of a sample to measure the tunneling current, providing atomic-scale images and information about electronic states.
