What are the Common Imaging Techniques Used in Nanotechnology?
Several imaging techniques are widely used in the field of nanotechnology:
Scanning Electron Microscopy (SEM): Uses a focused beam of electrons to produce high-resolution images of the surface of a sample. Transmission Electron Microscopy (TEM): Transmits electrons through a thin sample to capture detailed internal structures at atomic resolution. Atomic Force Microscopy (AFM): Measures the forces between a sharp probe and the sample surface to generate topographical maps. Scanning Tunneling Microscopy (STM): Utilizes the tunneling current between a conductive tip and the sample to create images of atomic-scale surfaces. Fluorescence Microscopy: Uses the emission of light by fluorescent tags to visualize specific components within nanostructures.
