For decades, the ability to visualize the chemical composition of materials, whether for diagnosing a disease, assessing food ...

The UC Davis device exploits the properties of photon-trapping surface textures (PTST), surface modifications that enhance the light absorption capabilities of silicon photodiodes in the near-IR range ...

Researchers have miniaturized a spectrophotometer onto a single chip that can analyze any wavelength of visible light and part of the infrared spectrum (Science 2021, DOI: 10.1126/science.add8544).

For decades, bulky spectrometers have been the main tools for understanding how things are made of chemicals (a thing called composition). Spectrometers are a type of lab equipment that uses prisms or ...

A new electron paramagnetic resonance (EPR) spectrometer aims to open the technology to a larger pool of scientists by making it cheaper, lighter, and easier to use without needing an experienced ...

Researchers have successfully demonstrated a spectrometer that is orders of magnitude smaller than current technologies and can accurately measure wavelengths of light from ultraviolet to the ...
