Laser-based technologies like LIBS, Raman, and NIR spectroscopy are transforming food safety by enabling rapid, ...

Researchers from Shibaura Institute of Technology have developed fluorescent dyes based on nitrogen-rich pyrazinacenes that exhibit strong, tunable fluorescence between the visible and NIR/SWIR ...

"The switch away from using artificial coloring came as Ben and his family started researching more about dyes and color additives in the food their family was consuming," Judy Klosinksi said.

Significant progress has been made in the theoretical design of near-infrared II (NIR-II) fluorescent dyes by a team jointly led by Associate Professor Zheng Xiaoyan from the School of Chemistry and ...

Abenacianine for injection’s imaging component is the near infrared (NIR) dye indocyanine green (ICG), which is compatible with all commercially available NIR intraoperative imaging systems that ...

3 Therefore, validating the pigment concentration is key. Analysis by Vis-NIR spectroscopy is described in the following section. Triphenylmethanphenazin and azo dyes are traditionally used for ...

The NIR-II small-molecule dye developed by the lab of Rice University chemist Han Xiao is featured on the cover of the Dec. 28 issue of the Journal of the American Chemical Society. Credit: Xiao ...

"Generally speaking, the reason a NIR-II dye molecule tends to be big is because it is a conjugated structure with many double bonds," he continued. "This is a true problem and the reason why we ...

In addition, TQT-based D-A-D dye, FT-TQT, demonstrates real-time cerebral and tumor vessel imaging capability. NIR-II fluorescence imaging achieves dynamic monitoring of tumor vascular disruption ...
