    Researchers developed a new superlensing objective lens, achieving 100 nm resolution for super-resolution microscopy. This breakthrough overcomes conventional microscope limitations, enabling clearer imaging of subdiffraction features.

    Area of Science:

    • Optical microscopy
    • Nanotechnology
    • Biophysics

    Background:

    • Conventional microscope objective lenses are limited by diffraction, restricting resolution to 250-300 nm under white light.
    • Subdiffraction feature resolution requires innovative optical solutions beyond current microscope capabilities.

    Purpose of the Study:

    • To propose and demonstrate a novel superlensing objective lens with enhanced resolution.
    • To achieve a two-times resolution improvement over conventional microscope objectives.

    Main Methods:

    • Integration of a conventional microscope objective with a superlensing microsphere lens via a custom adaptor.
    • Development of a label-free super-resolution imaging technique.

    Main Results:

    • Demonstrated a superlensing objective lens with 100 nm resolution.
    • Successfully imaged 100 nm features in both engineering (Blu-ray disk) and biological (adenoviruses) samples.
    • Achieved a two-times resolution improvement compared to standard objectives.

    Conclusions:

    • The developed superlensing objective lens significantly enhances optical resolution.
    • This innovation enables label-free super-resolution imaging of nanoscale features.
    • The work paves the way for generic optical superlens development, potentially transforming optical microscopy.
