Researchers at the Karolinska Institutet in Sweden developed a nanosensor based on surface-enhanced Raman spectroscopy or scattering (SERS). The proof-of-concept method uses flame-sprayed silver...

Moungi Bawendi, Louis Brus, and Alexei Ekimov have been awarded the 2023 Nobel Prize in chemistry for the discovery and development of quantum dots, which are nanoparticles small enough that their...

Physicists at the University of Würzburg have used light to propel micrometer-size objects in an aqueous environment and control them precisely on a surface with all three degrees of freedom...

The process of 4D printing is an extension of 3D printing, in which solid objects are created using materials that can change shape when exposed to certain stimuli like heat, water, or light. ...

Ximea’s MJ042MR-GP-P11-BSI-UV model was added to its portfolio of scientific cameras. It’s equipped with a Gpixel PulSar sCMOS sensor that is combined with Peltier cooling and USB3...

Two perspectives on the Future of Optics Dr. Adam Wax, Theodore Kennedy Associate Professor of Biomedical Engineering at Duke University’s Fitzpatrick Institute for Photonics and Director...

The invention of optical coherence tomography (OCT) has allowed physicians, researchers, and various industries to obtain very detailed 3D images of a material's underlying physical structure. The...

Currently, Fourier transform spectroscopy most often involves large benchtop devices that measure in the infrared (IR). However, recent innovations have simultaneously shrunk the technology and...

Raman, bio-Raman, and other bio-spectroscopy methods often require the detection of weak signals. The appropriate spectrograph and detection technology increase the measurement sensitivity, reduce...

Nanopositioning refers to the precise and controlled movement or manipulation of objects or components at the nanometer scale. This technology enables the positioning of objects with extremely high...

Scanning electron microscopy (SEM) is an advanced imaging technique used in microscopy to obtain high-resolution, three-dimensional images of the surfaces of solid specimens. SEM achieves this by...

Dewetting is a phenomenon in materials science and physics where a thin film or coating spontaneously undergoes a process of breaking up and forming isolated droplets on a substrate. This occurs due...

An atomic force microscope (AFM) is a high-resolution imaging and measurement instrument used in nanotechnology, materials science, and biology. It is a type of scanning probe microscope that...

National Photocolor is a manufacturer of off-the-shelf and custom pellicles. We offer a broad selection of pellicle beamsplitters, filters and windows for UV to IR applications. Many custom type...
