Three-dimensional (3D) imaging is essential for investigating cellular structure and dynamics. Traditional optical methods rely on adhesive or mechanical forces to hold and scan cells, which limit ...

Researchers have developed a new microscope that can visualize the optical response of surfaces at an unprecedented spatial resolution of one nanometer. This paves the way for optical microscopy of ...

Photoluminescence (PL) describes the process of light absorption and subsequent re-emission by a material and its characterization is a powerful tool for unveiling the optical and electronic ...

Smartphones are a potentially powerful platform for scientific instruments. Here, we demonstrate speckle spectroscopy with smartphone-level hardware. This technique promises greater performance ...

Add Yahoo as a preferred source to see more of our stories on Google. Microscopes have long been scientists’ eyes into the unseen, revealing everything from bustling cells to viruses and nanoscale ...

Introduction to SNOM: The Scanning Near-field Optical Microscope (SNOM) stands as a pivotal analytical tool in nanotechnology, enabling the visualization of nanostructures with resolution beyond the ...

Everyone who ever took a photo knows the problem: if you want a detailed image, you need a lot of light. In microscopy, however, too much light is often harmful to the sample—for example, when imaging ...

Confocal microscopy is a specialized fluorescence imaging technique that scientists use to acquire images at greater resolution than conventional microscopy. 1 In addition to scanning the lateral x ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

Microscopy is an imaging technique that enables us to see a world that would otherwise be invisible to us. Once upon a time, visualizing cells, microbes and other entities not perceptible to the naked ...

Researchers have invented an entirely new field of microscopy -- nuclear spin microscopy. The team can visualize magnetic signals of nuclear magnetic resonance with a microscope. Quantum sensors ...

Microscopes have long been scientists’ eyes into the unseen, revealing everything from bustling cells to viruses and nanoscale structures. However, even the most powerful optical microscopes have been ...
