High aspect-ratio micropillars are in strong demand for microtechnology, but their realization remains a difficult challenge, especially when attempted with soft materials. Here we present a direct ...

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 measurement of specific molecules in serum and plasma is essential in the diagnosis, treatment and management of many diseases. Traditional methods have used single assay techniques, whereby only ...

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 ...

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 ...

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 ...

Microspheres are microscopic spherical particles with applications in various fields, including drug delivery, diagnostics, and materials science. One of the key challenges in their preparation is the ...

PSL has developed a microsphere refiner for microsphere formulation, from small scale processes to commercial production. PSL, a manufacturer of filtration, drying and complete containment solutions, ...

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 ...

(Nanowerk Spotlight) A conventional optical microscope equipped with an oil immersion objective can resolve objects no smaller than about 200 nanometers – a restriction known as the diffraction limit.
