Several advanced techniques exploit echo phenomena at the nanoscale:
Ultrasound Imaging: By using nanoparticles as contrast agents, ultrasound imaging can achieve higher resolution and better tissue differentiation. Spectroscopy: Techniques like Raman spectroscopy rely on the reflection and scattering of light by nanomaterials to identify chemical compositions. NMR (Nuclear Magnetic Resonance): Echo-based techniques in NMR can provide detailed information about the molecular structure and dynamics at the nanoscale.
