How Do We Achieve Visibility?

Visibility at the nanoscale is achieved through a combination of advanced microscopy techniques. Some of the most significant methods include:
1. Scanning Electron Microscopy (SEM) - Uses focused beams of electrons to provide high-resolution images of the surface of a sample.
2. Transmission Electron Microscopy (TEM) - Passes electrons through a thin sample to produce detailed internal images.
3. Atomic Force Microscopy (AFM) - Employs a mechanical probe to map the surface of a sample at the atomic level.
4. Scanning Tunneling Microscopy (STM) - Uses a quantum tunneling effect to create images of surfaces at the atomic scale.
