The optical diffraction effect imposes a radical obstacle preventing conventional optical
microscopes from achieving an imaging resolution beyond the Abbe diffraction limit and …

Conventional optical microscopes are only able to resolve objects down to a size of
approximately 200 nm due to optical diffraction limits. The rapid development of …

Light microscopy is one of the most powerful techniques for nondestructive real-time
imaging of specimens at a resolution beyond the reach of human eyes. However, the spatial …

The resolution of conventional optical equipment is always restricted by the diffraction limit,
and improving on this was previously considered improbable. Optical super-resolution …

The resolution of an optical microscope is restricted by the diffraction limit, which is
approximately 200 nm for a white light source. We report that sub-diffraction-limited objects …

The spatial resolution of a standard optical microscope (SOM) is limited by diffraction. In
visible spectrum, SOM can provide∼ 200 nm resolution. To break the diffraction limit several …

Sub-surface nanostructures cannot be observed by scanning electronic microscopy or
standard scanning probe microscopy. They are also outside the resolution limit of standard …

Dielectric microsphere based super-resolution imaging is a promising approach to
overcome the diffraction limit of imaging in an optical microscope. So far, it still remains as a …

Microsphere based super-resolution imaging is a promising approach to achieve enhanced
optical imaging with an ordinary optical microscope. In this study, we propose a new …

Microsphere assisted microscopy is a facile and affordable super-resolution technique.
Here, we explored fully liquid-immersed high-index (n= 1.9, 2.1) microsphere assisted super …
