Materials with relatively small refractive indices (n< 2), such as glass, quartz, polymers,
some ceramics, etc., are the basic materials in most optical components (lenses, optical …

The diffraction limit is a fundamental barrier in optical science and engineering. It limits the
minimum feature size in surface patterning technologies, such as lithography and laser …

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 …

Fluorescence super-resolution microscopy has, over the last two decades, been extensively
developed to access deep-subwavelength nanoscales optically. Label-free super-resolution …

Quantitative phase microscopy (QPM), a technique combining phase imaging and
microscopy, enables visualization of the 3D topography in reflective samples, as well as the …

Microsphere-assisted microscopy currently benefits from a considerable interest in the
microscope-research community. Indeed, this new imaging technique enables the lateral …

This paper pertains to a long-standing debate about the quantification criteria and
mechanisms of optical superresolution in microsphere-based nanoscopy. Its super …

Nanomanipulation provides high operating accuracy and has been successfully applied in
many fields such as nanoparticle assembly, nanowire alignment, and semiconductor device …

We present a simple high-resolution approach for 3D and quantitative phase imaging (QPI).
Our method makes the most of a glass microsphere (MS) for microscopy and a glass plate …

One of the most significant developments in life sciences—the discovery of bacteria and
protists—was accomplished by Antoni van Leeuwenhoek in the 17th century using a single …
