For decades, scientists have tried to peer deep inside the human brain using beams of harmless near-infrared light. The technique, called functional near-infrared spectroscopy, or fNIRS, has become a ...

There are lots of situations where getting a look at the human brain can be very helpful. Unfortunately, our heads are famously opaque, so decades of research and development have gone into finding ...

Newer techniques using nanoparticles are less invasive, but some need bright visible light, which can harm any remaining ...

Shubhanshu Shukla, the first Indian astronaut on the International Space Station, is working to develop a brain-computer ...

Specifically, the nanomaterial absorbs 980-nanometer near-infrared light (which is relatively close to the red edge of the visible light spectrum).

Previously, near-infrared absorbing organic materials were treated as closed-shell molecules without unpaired electrons. However, a joint research group led by Associate Professor Takeshi Maeda ...

A Japanese research team has developed core–shell upconversion nanoparticles that can convert weak near-infrared light to visible light with high efficiency. By developing a near-infrared ...
