It accurately distinguished colors across seven out of its eight detectable wavelengths, and its readings at 620 nm were highly similar to commercial chlorophyll meters.

The new nanospectroscopy end station is based on a scanning optical microscope and enables imaging and spectroscopy with infrared light with a spatial resolution of more than 30 nm.

Conventional top Ag electrodes utilized for transparent solar cell applications typically range in thickness from 9 to 15 nm.

"It offers a simple approach to realize processing scales below 100 nm and opens new possibilities for laser nano-processing in various industries and scientific fields."

Remarkably, their study has showcased a spatial resolution of sub-40 nm for proton imaging; this holds tremendous promise for advancing various fields, such as materials characterisation, medical imaging and scientific research.
