A research group has discovered that near-infrared absorbing dyes, which had previously been considered to have closed-shell electronic structures, have an intermediate electronic structure, between ...

Imaging in visible light hits a wall when it comes to imaging in tissue for two main reasons: visible light is absorbed and scattered by tissue and tissue autofluorescence occurs chiefly in the ...

The team’s new compound can absorb electromagnetic waves in the NIR-II part of the spectrum, where waves can penetrate deeper into human tissue and generate heat, leading to photoacoustic emissions.

What is Surface-Enhanced Infrared Absorption (SEIRA) Spectroscopy? Surface-enhanced infrared absorption (SEIRA) spectroscopy is an advanced analytical technique that combines the principles of ...

Controlling a molecule is not always simple. For instance, the precise arrangement of electrons in an organic molecule determines the wavelengths of light it can absorb; this can be challenging to ...

(Nanowerk News) Near-infrared light, whose wavelength is longer than visible light, is invisible and can pass through many substances. Organic materials that efficiently absorb near-infrared light are ...
