What Imaging Techniques are Used in Nanotechnology?
Several imaging techniques are employed in nanotechnology:
Scanning Electron Microscopy (SEM): Uses a focused beam of electrons to create high-resolution images of the sample surface. Transmission Electron Microscopy (TEM): Transmits electrons through a thin sample to obtain detailed images of internal structures. Atomic Force Microscopy (AFM): Measures the force between a sharp probe and the sample surface to create topographic images. Scanning Tunneling Microscopy (STM): Uses the quantum tunneling of electrons between a sharp tip and the sample to generate images. Fluorescence Microscopy: Uses fluorescent markers to visualize and analyze biological and chemical samples at the nanoscale.
