    • Nanotechnology

    Background:

    • Near-field scanning optical microscopy (NSOM) aims to surpass the diffraction limit of light.
    • Conventional NSOM faces challenges with low signal strength and limited resolution.
    • Achieving nanometric spatial resolution with optical methods is crucial for advanced characterization.

    Purpose of the Study:

    • To develop advanced near-field probes for enhanced NSOM performance.
