Silicon fluorescent material developed enabling observations under a bright 'biological optical window'

NIMS MANA research groups and a Nagoya University research group jointly developed a silicon fluorescent material that is very low in toxicity and high in luminescence efficiency, compared to conventional materials. Under near-infrared radiation (NIR) at wavelengths of 650 to 1,000 nm—the range known as the "biological optical window"—that is capable of passing through living systems, the joint group succeeded in bioimaging using this new material.
