In addition to nano-hole structures achieved by contact mode, the microsphere femtosecond laser fabrication can also realize arbitrary structures on sample surfaces in non-contact mode. By lifting the ...

Controlling light within microscopic spaces is crucial for next-generation optical devices such as photonic integrated ...

What is microsphere nano-imaging? A microsphere is a spherical particle between one and one thousand micrometers (μm) and in diameter. 1,000 μm is the same size as one millimeter, while 1 μm is 1,000 ...

The conventional microscopy is limited by the diffraction limit which is 250 nanometers. Thus, it is rather difficult to resolve objects that are smaller than that. However, some improvements have ...

Optical measurement techniques collecting light intensity in the far-field such as conventional and confocal microscopy or coherence scanning interferometry (CSI) enable fast and contactless ...

Optical microscopic imaging resolution has a theoretical limit of approximately 200 nm within the visible light spectrum due to the far-field diffraction limit, which prevents the technique from being ...

A Linnik interferometer microscope is designed to take high-resolution images of the surface topography of a sample. The device works by splitting a beam of illuminating light in two, with one beam ...

Keratin microsphere gel, consisting of keratin-based microspheres that swell in water to form a gel, has shown efficacy in promoting hair follicle growth in murine models. Its potential application as ...
