Penetrating ever farther into the submicron world, microscope designers have broken through the diffraction barrier that once stood between researchers and the mysterious depths of the nano world.

Near-field optical microscopy encompasses a family of methods that overcome the classical diffraction limit by accessing evanescent electromagnetic fields within a few nanometres of a specimen’s ...

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 ...

Atomic force microscopy (AFM) is a technique widely used in nanoscience and materials research offering high-resolution imaging of surface topography with sub-nanometre precision. In non-contact mode, ...

Understanding the interaction between light and matter at the smallest scales (angstrom scale) is essential for advancing technology and materials science. Atomic-scale structures, such as defects in ...

Near-field optics operates on the principle that when light interacts with objects smaller than its wavelength, it can produce an evanescent wave that decays exponentially with distance but provides ...

Over the past decade, breakthroughs in nanofabrication technology have enabled the structuring of various materials down to 10-nanometer or even atomic scale, ushering nanophotonic research into a new ...

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 ...

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 ...
